Leading Edge Sharpening System works extremely well for almost any sharpening scenario, outperforming many high-end sharpening systems currently on the market.
Designed for hobbyists and makers, Leading Edge Sharpening System is based on traditional concepts: 6" sharpening stones, modular approach, and standard diameter rods. It gives Leading Edge platform a very low cost of ownership in conjunction with unlimited upgradability. You are not limited to 3D-printed accessories designed by Leading Edge. You can use various compatible accessories and clamps made by Hapstone, TSPROF, Kazak, and KakBritva.
Leading Edge Core is a major step towards true "cross-platform" sharpening systems designed by Burt Joubert, creator of GearConnect, the bridge between famous sharpening systems and clamps designed for other platforms. Leading Edge Core goes far beyond that – customers can create hybrids where two sharpening systems are fused together. Work Sharp Precision Adjust becomes the first habitat for Leading Edge Core Upgrade, a key element of symbiosis. Leading Edge Core Upgrade accepts attachments designed for Leading Edge Sharpening System such as vertical knife support, scissors clamp, long blade attachment, etc.
