I have collected knives my whole life. I was never one for sharpening them. I have always sent them back to the Manufacturer to get the factory edge put back on. Last year when I was offshore, a welder asked me if I wanted him to sharpen my Spyderco Pacific salt, I let him and 2 hours later he brought it to me with a better edge than it had when new.
The Blade was not scratched in anyway and still looked brand new. He then laid a piece of paper on my desk and filleted it and I was amazed. I asked him to bring his sharpener for me to look at it. Anyway that was enough to convince me to spend $200.00 on the Edge Pro Apex Kit.
I bought it late last year and a few months ago I took it with me offshore and practiced on some older cheap knives. It took me about 2 days or 8 hours until I mastered it and now I can put a polished edge that is sharper than my Microtech knives come from the factory, It is nice never having to rely on anyone else to do this for me, this was money well spent
