I would avoid any type/kind of "kit" for the simple reason is "for the most part you Can't.!!! Take it with you" Most of those things have to be "set up" right angle rods for different blades" "hard to do big blades with" "need a flat surface" and about 15-20 others I could think of. I started sharpening blades at the age of 6 years old. (No Joke) My Father worked for Norton abrasives when I was very young. (He has been gone for many years now) But my Grandfather was a "I can build/make what you need" and did many times. (even blades for a logging camp in upper Canada in 1907-1911 made from the saw blades and deer antlers that were abundant) I watched him use a stone to put a shaving sharp edge in just 20-30 seconds. I was hooked.!!! I got a gift from my Dad (A Norton stone) at the age of 6, and started to sharpen ALL the blades in the house. Sure I have tryed most All of the Gagets (sp. my choise of wording) and put them in the trash. I have used this same Norton for over 40 years, and you can't tell the difference from a 2 year old one. (seems they get better with age) But if you learn to use a good stone, (I think any blade owner should know how to do this, its been history for 1000s of years) And start to pratice on old blades, or ask a good Man/Woman how they do it (2-3 min lesson) And you will be able to take it anywhere.!! any angle, any blade steel, any length, and with a small bit of learning you're in the biz. I like the Norton India combination stones, so you can use it to get a butter knife sharp if you felt like it. They are cheap, last a lifetime, and will put a hair popper edge on Any blade you have. I've been doing it for over 40 years, and on 1000s of blades, and every person (I'm a knife maker myself) I had done their edge, was more than pleased. (I'm still asked by hunters and chefs every year to put an edge on their blades to this day) So I would say, learn a simple way to put a *good* easy to do edge on with a stone, and then you are set for life. No need for any attachments or spend big $$s. And once you get the hang of it, you will be Very self satisifed with your work. Well thats my opinion, and I know its millions of others as well. We need to keep our basic skills, and not Gagets, as I see it. Plus its kinda fun. Enjoy and Happy Hollidays. edgy :thumbup:
