1.1 Why hasn't OUMO published a buying guide before?

We assumed this hobby has a learning curve, and that most people would have done their research before stepping into artisan-grade brushes. But lately, more newcomers are joining, and facing our system-driven brand, they can feel lost. So now feels like the right time.

1.2 Who wrote this guide, and why should I trust it?

I'm Carry. I've been wet shaving for over a decade, before OUMO even existed. Since 2015, I've personally used well over a thousand brushes. OUMO also collects feedback from the global community. Combine that with my own experience, and I believe I can offer you a genuinely useful reference.

2.1 What types of shaving knots does OUMO offer?

Four types:

• Hog Badger – strong backbone, balanced performance
• Dog Badger – softer, more luxurious feel
• Bristle – more resilient, precise, affordable
• Synthetic – easy to lather, low maintenance, long lifespan, various textures, great value

2.2 How do I choose among them?

Start by picking which category appeals to you. Each type behaves differently. Within each type, we offer multiple grades based on raw material tier. Price reflects scarcity, but more expensive doesn't automatically mean better for you.

2.3 What determines a knot's performance besides material grade?

Tuning matters just as much—density, bleaching level, bleaching method, selection process. Craftsmanship often affects the final feel more than the material itself. The material sets the ceiling; the craft decides how close you get.

3.1 Why did OUMO change knot sizes from 22-24-26-28-30 to 21-23-25-27-29 mm?

Because of a common misunderstanding. Hand-tied knots and traditional glued knots are measured differently. Hand-tied knots have only basic reinforcement at the base; glued knots have a glue base matching their nominal size. People assume the glue base diameter equals the knot size, but the real measure is the hair bundle.

Badger hair is thickest at the waist, narrower at the base. A knot that reaches 28 mm at the waist may measure 0.1–0.3 mm smaller at the base. Hand-tied knots measure pure hair, not glue. To avoid confusion, we down-sized our labels by one step. A 25 mm labeled knot is actually very close to 26 mm.

3.2 Why does a handle bore need to be larger than the knot size?

Example: a handle for a 27 mm knot has a bore of about 28.5–29 mm. First, it makes installation smooth. More importantly, dense Badger knots expand when wet. The gap releases that expansion naturally instead of suppressing it. We've tested this extensively.

Some handles now use funnel-shaped openings—an angled top section to better manage expansion pressure. If you insist on zero clearance, performance loss is small, but the expansion force can crack a thin-walled handle. Don't underestimate it.

3.3 What is "standard LOFT," and should I follow it?

Standard LOFT is a reference point, not an absolute correct value. If you're new, start there. It's set to show the knot's full character and based on years of experience and current market preferences.

But wet shaving is personal. No universal best setting exists. If you prefer fluffier feel or softer backbone, increase LOFT up to 10%. We'll warn you if you approach the knot's limit, and explain what you gain and lose. Small changes of 1–2 mm are safe.

Example: Emperor's LOFT is set low to fix Silvertip's historically weak backbone. If you love traditional Silvertip feel, raise it 2–4 mm.

And LOFT isn't permanent. We use low-temperature silicone. Heat the glued area to about 90°C, and you can remove and reset the knot. Finding your ideal LOFT is part of the journey.

4.1 Can you walk me through the Hog Badger knot lineup?

This is our largest category, including: 5th, 7th, The Unsullied, Rorschach, ACE, Manchuria, Tyrant, Elixir, Epoch, Zhuque, and Origin.

We group them into three tiers:

Daily Use: 5th, 7th, ACE, Manchuria

• ACE and Manchuria meet any demanding user's needs. Balanced. Top recommendation for first-timers. Manchuria uses higher-grade material and performs better overall.
• 5th and 7th offer great value and entry-level high-end quality. Ideal for daily use without guilt.

Luxury Collection: Tyrant, Zhuque, Origin

• These three are the market's peak, excelling in one or several areas.
• Tyrant costs less than Zhuque and Origin due to material rarity, not performance gap. Visually: striking white tips, wide black band. Performance: slightly stronger rebound and smoother feel than Manchuria. Real value is collectability and longer lifespan—thicker hairs, longer tips, minimal bleaching needed.
• Zhuque and Origin are OUMO's price ceiling. Zhuque tops natural Hog Badger performance; Origin tops finest two-band. Both use the highest-grade hair—extra-long tips, wide black bands, thick shafts—plus our strictest selection. Built for collectors seeking the ultimate.

Specialist Series: The Unsullied, Rorschach, Elixir, Epoch

• The Unsullied: untreated, strong bristly feel. Intact cuticles produce creamy lather. Less soft than Zhuque.
• Rorschach: lightly bleached to remove prickliness, retains raw texture. Not as soft as processed knots, not as gritty as untreated. For those who want natural feedback.
• Elixir: maximum rebound. Thick hairs, low density, pronounced bulb shape. For fans of sharp, linear snap.
• Epoch: made from Xinjiang Tianshan Badger hair—extremely rare, combines Hog and Dog Badger strengths. Only choice for untreated knot with both elasticity and softness.

4.2 Are Hog Badger knots always the best choice?

They lead in overall capability. Different grades and tuning emphasize specific traits or find balance. Parameters evolve with preferences. For example, 2016–2019 favored dense, strong-backbone knots. We adjust as tastes shift.

4.3 What about Dog Badger knots?

They're less varied because Dog Badger hair is very consistent—less "playability." We offer three models:

• Silk: value leader, good affordability, slightly lower rebound. Great if you like wide, mushroom-like splay.
• Emperor: highest-grade Silvertip, traditional luxury benchmark. Plush feel with firm backbone from premium material and density.
• Kirin: untreated, same grade as Emperor. Soft and smooth with subtle natural grit.

Dog Badger knots are closer to the classic top-tier brush: soft, smooth, luxurious. Hog Badger has taken over the spotlight with finer grading and processing, but Dog Badger's natural silkiness can never be replicated. Genetic limitation.

4.4 Tell me about OUMO's synthetic knots.

Our Super Fiber series is fully controlled in-house—from polymer pellet selection to fiber structure, diameter, blend ratio, and color. We don't just buy what suppliers offer. We build a systematic, traceable synthetic line.

Three models:

• ST-1: strong backbone, soft with slight texture
• ST-2: cloud-like ultra-soft, gentler rebound
• ST-3: combines high rebound and softness, new fiber structure

ST-1 and ST-3 come in two densities. ST-2 is max-density only due to its material parameters.

5.1 How do I choose a brush handle?

Three tiers:

• Standard ($40–$70): Resin, wood, aluminum, multi-material. Daily use. Excellent value.
• Master ($100–$180): Stabilized wood, ebonite, reconstituted turquoise, plus finishes like glaze, foil inlay, fluid art, 5-axis carving. Balances usability and collectability.
• Limited/Flagship ($250+, often $300+): Bronze, titanium, limited ebonite, Chinese lacquer, extreme 5-axis machining, multi-material assembly. Technical ceiling. Collectible value first, practicality second.

For daily use, Standard is enough—it's already artisan-grade. Master adds refinement. Limited is about peak capability. Choose based on your needs. Don't judge a Limited edition's ergonomics against a daily driver—they have different purposes.

6.1 Any final advice?

If you've read this far, you'll find the right brush. Trust your preferences, use the framework we've laid out, and enjoy the process.

1.1 为什么OUMO以前没有发布过购买指南？

我们默认这个爱好有一定的学习曲线，大多数人在踏入工匠级剃须刷的世界之前，已经做过足够的研究。但最近有更多新人加入，面对我们这种体系驱动的品牌，容易感到不知所措。所以现在觉得是时候了。

1.2 这篇指南是谁写的，我凭什么相信他？

我是Carry。在OUMO成立之前，我已经有超过十年的湿剃经验。从2015年至今，我亲手使用过超过一千支剃须刷。OUMO也长期收集全球社区的反馈。结合这些用户反馈和我自己的经验，我相信能给你一份真正有用的参考。

2.1 OUMO提供哪几种剃须刷结？

四种类型：

• Hog Badger（猪獾） – 支撑力强，性能均衡
• Dog Badger（狗獾） – 整体更柔软，触感更奢华
• Bristle（猪鬃） – 弹性更强，指向更精准，价格更亲民
• Synthetic（合成纤维） – 易起泡、易打理、几乎无需养护、寿命长、多种触感可选，性价比极高

2.2 我该怎么选？

先决定你喜欢哪一类。不同类型的体验差异很大。在OUMO的分类体系里，每一类又分多个等级，主要由原料等级决定。简单说，价格反映原料的稀缺程度，但越贵不一定越适合你。

2.3 除了原料等级，还有什么决定刷结的表现？

调教同样关键——密度、漂白等级、漂白工艺、筛选工艺等。很多时候，工艺比原料更能决定最终触感。原料决定上限，工艺决定你能多接近那个上限。

3.1 为什么OUMO的刷结尺寸从22-24-26-28-30改成了21-23-25-27-29毫米？

坦白说，这是因为一个常见的误解。Hand-tied Knot和传统带胶座的Knot，测量方式本质不同。Hand-tied Knot底部只做了基本加固，而传统胶座Knot底部有一个符合标称尺寸的胶块。人们习惯认为胶块直径就是Knot的直径，却忽略了最关键的部分——獾毛的实际填充量。

獾毛最粗的部位在腰段，底部更细。腰段能达到28毫米的Knot，底部可能小0.1到0.3毫米。Hand-tied Knot量的是纯毛束直径，不是胶块直径。为了避免混淆，我们把标称尺寸缩小了一号。标称25毫米的Knot，实际尺寸无限接近26毫米。

3.2 为什么刷柄的开孔要比刷结尺寸大？

举个例子：装27毫米Knot的刷柄，实际开孔大约在28.5到29毫米之间。首先是为了确保安装顺利。更重要的是，高密度的獾毛刷结湿水后会膨胀。预留空隙是为了释放这种自然膨胀，而不是强行压制它。这是我们经过大量测试后做出的选择。

有些刷柄我们现在已经开始采用漏斗形开口——上半部分带有一个打开角度，更好地释放膨胀压力。如果你非要零空隙安装，也可以，性能损失不大。但膨胀力可能会撑裂刷柄，尤其是薄壁刷柄。不要低估湿獾毛结的膨胀压力。

3.3 什么是“标准LOFT”，我应该照着用吗？

标准LOFT本质上是一个参考点，不是绝对的正确值。如果你是新人，从默认LOFT开始完全没问题。这个标准基于两个考虑：第一，它能完整呈现刷结的全部特性；第二，它建立在多年经验和当前市场偏好的基础上。

但湿剃是非常个人化的爱好，不存在普适的最佳设置。如果你喜欢更蓬松的触感或更软的Backbone，可以在标准基础上上调最多10%。如果调整接近刷结的极限，我们会第一时间提醒你，并告诉你得失。1到2毫米的小幅调整完全安全。

举个例子：Emperor的LOFT我们故意设得偏低，是为了解决Silvertip长期以来的痛点——Backbone偏软。但如果你喜欢传统Silvertip的感觉，这个设置可能不适合你，这种情况下可以上调2到4毫米。

另外，LOFT不是永久锁死的。我们用的是低温硅胶，把刷柄灌胶部分加热到90摄氏度左右，就可以轻松拔出刷结重新设置。找到适合自己的LOFT，本身就是湿剃体验的一部分。

4.1 能详细介绍一下Hog Badger刷结的阵容吗？

这是我们最大的类别，包括：5th、7th、The Unsullied、Rorschach、ACE、Manchuria、Tyrant、Elixir、Epoch、Zhuque、Origin。

我们大致分成三个等级：

日常使用级：5th、7th、ACE、Manchuria

• ACE和Manchuria已经能满足任何苛刻用户的需求。非常均衡，也是我们对新客户的首推。Manchuria原料等级更高，综合性能更优。
• 5th和7th性价比极高，同时提供了入门级的高端体验。如果你想买一支日常用不心疼的刷结，这两款是首选。

奢华收藏级：Tyrant、Zhuque、Origin

• 这三款代表了当前市场的顶级选择，在某一方面或几个方面做到了极致。
• Tyrant价格远低于Zhuque和Origin，但主要是因为原料稀缺度不同，不只是性能差距。外观上：华丽的白色毛峰、宽阔的黑色腰段。性能上：比Manchuria回弹更强、触感更丝滑，但提升是渐进式的，不是断崖式。它的真正价值在于收藏性和更长的使用寿命——更高端的原料意味着更粗的毛发、更长的毛尖，只需极轻微的漂白就能释放性能。
• Zhuque和Origin是OUMO的价格天花板。Zhuque代表了天然Hog Badger Hair的性能上限，Origin代表了Finest Two Band的性能上限。两者都采用最高级别的獾毛——超长毛尖、极宽的黑色腰段、粗壮的毛径——加上OUMO最严格的筛选工艺。专为追求顶级的收藏家打造。

特种兵系列：The Unsullied、Rorschach、Elixir、Epoch

• The Unsullied：未经任何处理，颗粒感强。完整的毛鳞片结构能打出奶油状的泡沫。但受限于原料等级，柔软度和顺滑度不如Zhuque。
• Rorschach：极轻度漂白，只去除扎刺感，保留了大部分原始触感。没有全处理刷结那么软，也没有未处理刷结那么糙。适合喜欢自然反馈的人。
• Elixir：回弹力的天花板。精选粗壮毛发，低密度，更夸张的Bulb形状，把弹性推到极致。喜欢强烈线性回弹的人会爱上它。
• Epoch：采用新疆天山獾毛制成，极其罕见，融合了Hog Badger和Dog Badger两种獾毛的优点。如果你想买一支未经处理、同时具备弹性和柔软度的天然獾毛刷结，Epoch是唯一的选择。

4.2 Hog Badger刷结总是最好的选择吗？

它们在综合能力上确实占优。不同的等级和调教参数，本质上是在强化某一方面或寻找多方面的性能平衡。这些参数不是一成不变的，我们会根据市场偏好的变化进行调整。比如2016到2019年间，流行的是高密度、强Backbone的大刷结。随着口味变化，我们也在调整产品来满足当下市场的期望。

4.3 Dog Badger刷结呢？

Dog Badger的变种没有Hog Badger那么多，因为Dog Badger毛的性能一致性很高——换句话说，可玩性没那么强。我们目前提供三款：

• Silk：Dog Badger系列里的性价比之选。价格亲民，同时保留了顶级Dog Badger刷结的精髓。主要妥协是回弹稍弱，但如果你喜欢宽大的蘑菇形Splay，它是理想选择。
• Emperor：OUMO体系内最高级别的Silvertip，传统意义上的奢华标杆。触感丰盈柔软，同时用顶级原料和极致密度提供了坚实的Backbone。
• Kirin：未经处理的天然Dog Badger刷结，与Emperor同等级原料。触感更原始——柔软顺滑中带有细微的自然颗粒感。

Dog Badger刷结更接近传统意义上的顶级剃须刷：柔软、顺滑、奢华。虽然Hog Badger凭借更精细的分级和加工逐渐抢走了风头，但Dog Badger那种天生的丝滑感，是Hog Badger永远无法复制的。这是原料基因决定的。

4.4 说说OUMO的合成纤维刷结吧。

我们的Super Fiber系列是全链条自主控制的——从原料颗粒的选择，到纤维结构、丝径、配比方案、配色方案，全程把控。我们不像是其他品牌那样“工厂有什么就拿什么”。我们要做的是有体系、可追溯、能解释性能来源的合成纤维系列。

目前三款：

• ST-1：Backbone强，触感柔软带轻微颗粒感
• ST-2：云朵般极致柔软，回弹较温和
• ST-3：同时具备高回弹和柔软触感，首次采用全新纤维结构

ST-1和ST-3各提供两种密度选项。ST-2因其原料参数的特殊性，只有极限密度一个选项。

5.1 刷柄怎么选？

三个等级：

• 普通级（$40-$70）：树脂、木材、铝合金、多材料混合。日常使用，性价比极高。已经是工匠级品质。
• 大师版（$100-$180）：稳定木、Ebonite、人造绿松石等珍稀材料，加上Glaze、贴箔、流体画、五轴雕刻等工艺。兼顾使用价值和收藏价值。
• 限量版/旗舰版（$250+，常达$300+）：青铜、钛合金、限量Ebonite、中国大漆、极端复杂的五轴雕刻、多材料拼接装配。代表OUMO当时的技术上限。收藏价值优先于实用性。

日常使用的话，普通级完全足够。大师版更考究。限量版是关于工艺巅峰的展示。根据自己的需求选。不要因为限量版的外观和工艺复杂度，去抱怨它的人体工学不够完美——它们的设计初衷本就不同。

6.1 最后还有什么建议吗？

如果你有耐心读完这篇指南，我相信你一定能找到真正适合自己的那一支。相信你自己的偏好，用我们提供的框架去判断，享受这个过程。
