Learn Hub

Most grinders feel similar on day one. The difference shows up months and years later.
This Learn Hub explains how material choice, machining precision, and mechanical balance affect grind consistency, smoothness, and long-term wear. These guides are written to help you understand what actually matters when choosing a grinder, whether you are comparing aluminum vs stainless steel, evaluating teeth geometry, or thinking about ownership over time.
Rather than trends, coatings, or short term performance claims, this library focuses on fundamentals. Each section breaks down one core principle and links to deeper explanations so you can make an informed decision based on how a grinder is built and how it ages with use.
Materials and Purity
Material determines how a grinder wears, how it reacts to friction, and how consistent it feels over time. These articles explain the differences between common grinder materials and why stainless steel purity plays a critical role in longevity and performance.
Aluminum vs Stainless Steel Grinders
A detailed comparison of how aluminum and stainless steel behave under repeated grinding, friction, and long term use, including durability and material stability considerations.
Why 304 Stainless Steel Matters
An explanation of what 304 stainless steel is, why it is harder and more expensive to machine, and how it affects longevity, corrosion resistance, and precision.
Common Grinder Materials Compared
A neutral reference comparing 304 stainless steel, 303 stainless steel, aluminum, plastic, and ceramic coated metals, with a focus on durability and aging behavior.
Engineering and Performance
Smoothness is not accidental. These guides explain how teeth geometry, tolerances, and mass distribution affect grind efficiency, torque, and overall feel during use.
Why Weight and Balance Matter More Than Sharp Teeth
How mass distribution creates natural torque, reduces effort, and produces consistent feedback compared with relying on aggressive teeth.
Teeth Geometry and Material Flow
How tooth count, tooth geometry, and hole layout work together to control consistency, reduce regrinding, and maintain predictable performance over time.
How Precision Machining Makes the Specular OG1 Turn Smoother
Why tolerances, concentricity, and alignment matter, and why stainless steel exposes errors instead of hiding them.
With or Without the O Ring
How the optional O ring changes friction, sound, and feedback, and why stainless steel allows this choice without durability tradeoffs.
Longevity and Ownership
Most grinders are designed as consumables. OG1 was designed as a durable tool.
This section will expand over time with practical guides on aging, wear, maintenance, and long term care.
How These Principles Come Together
Durable materials, balanced mass, and precise alignment are not separate ideas. They reinforce each other.
OG1 is built around these constraints from the start.

If you prefer, you can start with materials and work toward performance. Either path leads to the same conclusion. Control comes from integrity.
