Oddly, over the many years of using Stanley knives it never occurred to me that I could have sharpened them, in a pinch.1st post of many more i hope, Took a bit of scrap in today and found a big metal bin full of straight blades...i bought this lot for £4, should keep me going for a while.
The bastids caught me with their Gillette model marketing.

I remember seeing a carpet fitter doing that, every few minutes he would stop and dress the blade with a stone.

reason being they are only hardened on the cutting edge and as soft as sh,,it underneath so wont hold an edge for long

Boy thats a find - for a roofer cutting felt...
Well done...
Wait until he discovers they are scrap from a pre-production run . . . not yet hardened . . .
We have thousands of 3.3mm twist drills in our place for a trial . . . into the scrap afterwards . . . lots of disappointed people to discover they were less then suited for actual drilling - no point doing trials with fully finished items, when the basic shape is all that is needed.

I'm forever using knives with blades that are long past being sharp, and part of that is because I'm never quite sure what to do with the old ones. I asked the local council about disposal and apparently I'm supposed to do something convoluted including taking them to the tip, which sounds like a lot of messing around. What do you do with old knife blades? There's a scrap bin where I keep my cars, but I'm aware that the scrap man digs the stuff out to take away, it's not a big set-up where they lift the scrap bin and tip it into a truck, so I don't want to be responsible for slicing his fingers open.
ah..Maybe i won't bother sharpening old ones then, unless i'm stuck for one and the shops are shut
Wizz the grinder along the edge to take the sharp edge off, then all your left with is a metal offcut that can safely go in the scrap bin.

Thanks, I did have a go at grinding the edge off one but it didn't help a lot, as you say the small offcuts of steel that I put in the same bin are probably just as sharp.
I found the reply I'd got from the council when I asked: "Steel blades should not be placed in your waste bins at all but can be placed into a metal container and taken to a Household waste and recycling centre where bladed articles can be disposed of."

Bit like the old story of the contraceptive manufacturers sending rejected samples to their advertising Co. when designing a new presentation display.

And once you have enough practice you can move on to welding razor blades together
