Copper pipe to sell to use as a cutting instrument?

[Curiousgeorge]

I’m after some copper pipe to use to act as a knife to cut plastic wrapping off sheets of steel.
Also, is the pipe with a squeezed end the best way to do this?

It might just be me but I don’t get this?

Are you looking for a copper bladed knife? If so let me know when you find one

Or do you want a copper pipe handle on an existing blade? This I’ve seen before on a big hacksaw blade

Sorry, I mean there is some plastic wrapping on some stainless steel sheets and using copper to cut the sheet is perfect because it’s sharp enough to cut the plastic but not hard enough to mark the steel. I just need more!

Flattened copper pipe is fine, just file an edge on it and don't press too hard, there is a bit of a knack to it to avoid scratching the sheet, I also use a hard plastic knife edge made from plastic curtain rail, needs sharpening more often than copper but is much safer for the finish on bright annealed or mirror polished than copper,

You could try a good quality and stiff paint stirrer with an edge on it

I use a blow torch, one of those little kitchen jobbies. It melts so quickly it won’t stick to the innards if it’s the right sort of wrapping.

Your mileage may vary...

fingernails?

but i'd look at buying a plastic spudger/trim tool.

Box cutter?

Safety box cutter or Film cutter, no need to faff about with copper.

That's what I was thinking, sometimes known as a "fish cutter" though other styles exist.

Side of a 20p piece worked for me - cut through the laser film, didn't mark brushed or 2B finish stainless. Might not want to try it on mirror!

In pound land you can often get two plastic bag slicers that are a pointed plastic jaw cast round a sharp blade you can cut several thicknesses of shrink wrap with them ….. Ha Ha just seen Makers post . them's the beasts.
