Leading Edge Universal Upgrade enhances the capabilities of WorkSharp Professional Precision Adjust knife sharpeners with features of the Leading Edge sharpening platform. The Universal Upgrade includes:
- Leading Edge Core with a magnetic working table (one magnet block) and a three-point knife guide
- Long Blade Magnetic Support (two magnet blocks)
- Vertical Support/Scissors Clamp - a dual-purpose attachment that can be used for knives that don't remain stationary and for scissors
The Universal Upgrade utilizes three removable magnetic blocks measuring 1.5 x 0.5 x 0.25 inches with powerful N52-grade neodymium magnets. The Knife Guide allows you to position a knife precisely and symmetrically when flipping. The Universal Upgrade is equipped with a set of front screws for attachments. A 2.5-mm hex Allen key or screwdriver is required to work with the attachments (not included).
Attention! The product images are for illustration purposes only. Long Blade Magnetic Support and Vertical Support are not intended to be used simultaneously.
Leading Edge Sharpening System is the only 3D-printable sharpener that can sharpen knives, scissors, and other edged tools. It has a magnetic knife holder, a three-point knife guide, optional accessories such as vertical knife support, scissors clamp, long blade attachment, fine-tuning, convex stone holder, and various knife clamps. 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.
