Knife makers and woodworkers, these Woodriver mosaic pins are absolutely perfect for adding that special touch to your projects. At 4mm x 120mm (that's 5/32 x 4-23/32 inches), they're the ideal size for most knife handles and craft projects. The pattern is beautiful - with a 5/32 brass outer tube surrounding stainless steel rods in different sizes that create this eye-catching geometric design. I've used these for knife scales, and they not only look amazing but actually help secure the handles to the tang. They cut easily with a hacksaw, and you can file and sand them smooth for a perfect finish. The recommended drill bit size is 11/64, but definitely test on scrap wood first to get the fit just right. Beyond knives, they're great for decorating turned pieces, boxes, clocks - anywhere you want to add some metal accent details. The quality is solid, and the materials don't corrode or tarnish easily. Whether you're a professional knife maker or a hobbyist looking to upgrade your projects, these mosaic pins add that professional touch that makes your work stand out. They've become a staple in my workshop because they're so versatile and always get compliments on finished pieces.
