Single Edge Safety Razor Blade Holder

thingiverse

Every crafter working with single edge safety razor blades knows they're great for cutting various materials, but sometimes uncomfortable to hold. Especially when cutting through tougher materials like leather, the thin metal safety strip pushes deeply into your finger and hurts after a while. These blade holders are meant to mitigate this problem by offering a more comfortable grip. I have designed three different base thicknesses - small, medium, and large. I also added features that improve functionality, namely knurled sides for improved anti-slip gripping as well as a finger rest for easier application of pressure while cutting. You can find different combinations of those thicknesses and features here. All blade holders function the same way: the top has a covered slot which is pushed to the side using the side of the blade, then the holder can be slipped over the back/spine of the blade and snap into place, securing the blade. It should work with pretty much all regular single edge safety razor blades. If you have any ideas for improvements, I want to hear them. While I'm happy with some of those versions, there's always room for tweaking or different designs.
