I guess it depends on the size of the bank. I bought a Spyderco Triangle sharpener when they first hit the market. That was better than 12 yrs or so ago. Purchase price over 12 years = a pretty good deal IMHO. It is still going strong. It's easy to use and works on just about anything.What's everybody do to keep their carry blades in top shape? I keep mine rubbed down with a little CLP from time to time and sharpen when needed. I need a better sharpener though. Any advice on a good sharpener for light duty that won't break the bank? I have a pair of Spyderco Natives, a Kershaw Chive and a few cheapo autos.
