The 2.75″ length fits standard handle segments, and the contrasting fill enhances visibility against darker woods or composites. A versatile choice for mid to large fixed blade knife designs, especially where stainless is preferred for longevity.
Mosaic Pin 0.156″ Copper/Brass & Copper (Model 512CBC)

This 0.156″ mosaic pin pairs copper outer with brass and copper inner materials, offering a warm, intricate look for smaller handles. The double inner copper elements create a multi-tone effect that stands out against wood, micarta, or polymer scales.

Buying Guide: Key Purchase Considerations For Mosaic Knife Pins
- Diameter and fit: Choose pins that align with your handle’s pin holes. Common sizes include 0.156″ (5/32″) and 0.250″ (1/4″).
- Material combination: Copper, Brass, Stainless, Aluminum, and combinations affect appearance, corrosion resistance, and strength. Consider the blade steel and expected use when selecting outer/inner materials.
- Length: Ensure the pin length accommodates your handle thickness and tang depth. Longer pins offer more anchoring points but may require extra prep.
- Finish and fill: Black fill or contrasting fills enhance mosaic visibility. Fill color choice can affect the perceived depth of the design.
- Compatibility with handle scales: Standard USA sizing helps ensure your DIY project has a reliable fit with common pins and tangs.
- Aesthetic goals: Decide between traditional warm tones (brass, copper) and modern stainless or aluminum combinations for your project’s style.
- Durability for use-case: For kitchen knives, corrosion resistance matters; for outdoor or fixed blades, consider wear resistance and ease of maintenance.
- Availability and sourcing: Check for consistent supply of the specific model (inner/outer material pairing) to maintain uniformity across a project or batch.
- Installation considerations: Pre-drill holes to match pin diameter and ensure proper alignment for both decorative and structural purposes.
These considerations help knife makers select mosaic pins that align with project goals, whether prioritizing visual impact, longevity, or ease of fabrication. The highlighted options cover a range of materials, diameters, and lengths to fit common DIY handle projects.
