Knife, Scissors, Chisel & Razor Sharpener - Leading Edge System

This is my "Leading Edge" Sharpening System.

NOTE - The LATEST (Major upgraded) version of my system will soon be available as a ready-to-assemble kit from https://www.gritomatic.com . I will not be updating this version on Thingiverse any more, but I will leave it here for free printing.

NOTE - There is NO need to print all the parts. It depends on what type of sharpening you want to do and how you want to customise my sharpener - only print the parts you need. For a basic version of my sharpener (for knives and scissors only), I recommend only printing the following part numbers - A,Bv2,C,D,E,F,G,H(For Scissors),K(For Large blades),M,N.

NOW WITH CLAMP BARS for TSPROF, Blitz, Hapstone (R2 Lite) and KakBritva (Side and Wide Central) clamps as an optional extra.

If you do not want to use the primary magnetic knife mounting method, then I recommend using one of the metal clamps mentioned above, or optionally my knife clamp design can be CNC milled from metal.(CNC .step files available for download) If you want to use the knife clamps in the download files, it's best when CNC milled from metal.

My system can sharpen knives, chisels, straight razors, scissors, scalpels and countless other tools.

This is the only available 3D printable Knife, Scissors, Chisel, Straight Razor and tool sharpener. My system works very well for almost any sharpening scenario that you would need and works as well or better than any sharpening system currently on the market. It has a magnetic knife holder, a 3-point horizontal knife guide, vertical knife support, scissors clamp, straight razor 2-point guide, large blade sharpening attachment, convex sharpening stone holder and an optional rotating knife clamp (if desired). It also has a fine tuning adapter for extremely accurate sharpening angle adjustment.

One of the best places for purchasing your sharpening stones for my system is from https://www.gritomatic.com . They have a huge selection of every stone your heart desires and they have one of the best selections of sharpening abrasives on the internet. I also have optional stone holders for Lansky stones and Spyderco triangle hones.

Sharpening angle range approximately 0-50 degrees, depending on if the knife clamp / knife guide / straight razor guide / scissors clamp / chisel adapter being used.

I recommend using a digital angle gauge or angle measuring app on your phone to measure your exact sharpening angles. If you don't have a digital angle gauge, I also have my own design of a mechanical 3D printable one here for you - https://www.thingiverse.com/thing:4787548

Parts Needed:

(NOTE: All metric size M4 parts can be substituted with imperial size 8-32 parts. The 8mm stainless steel rods can be substituted with 5/16 stainless steel rods. I also added a separate .ZIP file for all the parts needed to make a 6mm stainless steel rod version of my system).

(NOTE: I will soon add a modified version of my system that can be assembled with M4 Nuts in stead of M4 brass inserts as an option.)
