I'm not a great sharpener, but I'm not terrible either. I have a sharpmaker, Smith's Diamond Tri-Hone and a few other gadgets that I can get a knife cutting paper with! Again, I'm not great but I can get them decently sharp. I just picked up a Worksharp Guided Field Sharpener. I do not know if it's the angle guides, the materials, or a combo. of all of this but I love the thing. I got my VG10 and S30 blades hair poppin' sharp WAY quicker and easier than anything else I have ever used. For those of you that are pros already on stones this may not mean as much haha. But for those of you that have tried several different sharpeners with so so luck, I HIGHLY recommend this thing! It's a great sharpener and all-in-one with no setup either. Pick one up!
