8 Inch Deluxe Blade Sharpening Kit for 6 Inch Bench Grinder - Professional Knife Sharpener Tool Made in USA - Perfect for Kitchen, Workshop & Outdoor Hunting Gear Maintenance

I screwed my grinding wheel up right of the bat by applying too much wax. I was able to salvage it by burning the wax off with a bic candle lighter. Anyway, the instructions are clear and precise, including details on regritting the wheel and tips on sharpening (although not too much detail on how much wax/lathing compound). Anyway, when I contacted customer service I got a call back directly from the owner! He explained how much wax to use -just briefly bump it once across the surface once before sharpening. As for the actual sharpening- it puts a razor edge on the hardest steels in a few seconds. I use one pass on kitchen and my 420HC blades, 2 passes on S30v, and 3 passes on s90v. Just like the worksharp, you've got to be careful not to grind the tip off. About the time the tip is halfway across the surface, pull it smartly towards you/off the wheel. As they say in the instructions, start off with knives from your junk drawer, not your Benchmade 940. You will need to decide to run your grinder front towards you or front facing away. What you are interested in is finding the best direction that allows you to clearly see what your doing, hold the best angle across the entire length of the blade, and comfort. You'll need practicing on the best angle, an even grind (especially on longer blades), and when to pull the knife away from the surface so as to not grind off your tip. Lots of light helps. Some knife steels will spark. Don't hold the blade without motion and don't press hard. On kitchen knives, put the edge flat (to maintain the low angle of the factory edge). If I find a grinder at a garage sale, I'll buy the leather stropping wheel. If you own or are considering the Worksharp, I'd suggest this system instead. It is faster to learn and faster to master and way faster to sharpen. I like my Worksharp, but the time it takes to replace the belts at each step is very annoying. Changing the belts isn't as easy as the videos suggest, it's hard to sharpen short and multi-tool blades, and it's way too easy to grind down the edge on the side of the blade where the belt runs bottom to top of you aren't super careful. Plus the guide only take works on larger/kitchen knives. Hope this helps you decide.
