Review on Precision at Its Finest: Work Sharp WSKTS-KO-W Knife & Tool Sharpener Ken Onion Edition by Jessica Thompson

Well the concept was great but yesterday finally confirmed what I thought was a problem. I used it on a friend's Japanese butcher knife and the angle on the guard is nowhere near the same. Now it has a really sharp edge on one side and a proper edge on the other. I don't know how to fix this, honestly I don't think this should happen! Just not with a tool designed to properly sharpen blades. It's rediculous! And now I have to try to fix it with my own hands, or tell him that his expensive cleaver is a crowbar. You can clearly see that the left side is much steeper than the right side. So this is what ruined my $300 MSK1 survival knife! And after posting this review for quite a while the seller doesn't seem to care and after emailing Work Sharp and leaving bad reviews on their website they don't care and it seems like they do Nor does Revain care . It's sad if there's nothing you can do to contact support or leave a review that can't be helped. So I repeat my previous opinion, do not buy this product!
