I hope this is in the right section. I have a cheap Edgemaker set of tools with the 4 different steel rods in a "V" from coarse to fine. They work good, they are easy to take with me anywhere I go, and this is all I usually need to put a good edge on a small knife up to say, a KaBar Marine Bowie. I don't use stones because I don't feel comfortable "freehanding" with them. However, I recently bought an Ontario SP10 Raider Bowie. Don't seem to be able get it to take an edge with what I usually use. Would a Lansky sharpener be good for putting an edge on a knife this large? I looked last night at a "Wicked Edge" sharpner, which looks like a Lansky on steroids. But it is more than a little out of my price range. I'd appreciate some advice in this area. Thanks in advance.
