Utility knife blade sharpener

 'In-and-Out' honing stone
 
(0) 		  [vote for,

I frequently use a utility knife at work (the kind that has a sliding lever at the top that extends or retracts the blade), and am forever replacing dulled blades.

How about incorporating a small honing stone in the handle, so that every time the blade is retracted/extended, it 'self-sharpens'? Maybe the stones could have very small springs behind them to keep an even tension against the blade as it is gradually honed away over many uses...

       I’ve seen many a self-sharpening device, but never one for a utility (razor) blade. +

       In the interest of efficiency, I never retract my utility knife but just jam it into the tool belt, and thus would never sharpen such a blade. I also find that I snap the tip off the blades occasionally, thus making sharpening a non-solution. But I did find that Home Depot now sells a quick change utility knife, so you just press a little button and VOILA! Much easier than unscrewing/disassembling the dern thang. With regard to the used blades, I just stash them away in some apples I give away at Halloween. Just kidding.   

       But the idea is good, and I did see somewhere a kitchen "cutlery set" that has sharpeners built into the wood block thingy, under the "StaySharp" trademark.

       I like it. Wilkinson Olfa.
Most of the carpet and linoleum installers that I know sharpen their Olfa, (retractable , snappable razor) blades to try and cut costs. If you could make one that self sharpened and was durable enough, these would sell.
I go through a fifty pack of blades every three weeks or so, and I'd buy one		   

       Nice first idea there, Ample. Welcome to the bakery.

       Shz sells self-sharpening sheaths by the seashore, surely?
