pegasus bridge Posted October 21, 2014 Report Share Posted October 21, 2014 After watching a clip on YouTube of a chap making a knife out of a putty scraper using an angle grinder, I decided to give it a go. It literally took a couple of minutes to cut and put a rough edge on it with a sanding disk. It took an hour with the lansky and polishing to finish, I'm pleased with how it turned out overall, going to try another shape knife the next time though.

pegasus bridge Posted October 21, 2014 Author Report Share Posted October 21, 2014 Yeah, copied the shape from one I had seen before. Quote Link to comment Share on other sites More sharing options...
FalconFN Posted October 21, 2014 Report Share Posted October 21, 2014 Simple and effective. You have to be careful not to overheat the steel whilst cutting though, as it could affect the hardness. Quote Link to comment Share on other sites More sharing options...
kent Posted October 22, 2014 Report Share Posted October 22, 2014 almost impossible to retain an good cutting edge unfortunately, though looks just fine Quote Link to comment Share on other sites More sharing options...
aris Posted October 22, 2014 Report Share Posted October 22, 2014 There are several videos on YouTube where people use old circular saw blades as the raw material for a knife. I think the challenging part is heat treating and tempering the knife afterwards to the correct hardness. Quote Link to comment Share on other sites More sharing options...
Dunkield Posted October 22, 2014 Report Share Posted October 22, 2014 The massive powered saw blades were use to make decent knives when I did my apprenticeship. This kind of thing. Quote Link to comment Share on other sites More sharing options...

Yep like that but the only thing you can do is keep quenching like sharpening a HSS drill, they make far better spatter removers than knives Quote Link to comment Share on other sites More sharing options...
bear-uk Posted October 26, 2014 Report Share Posted October 26, 2014 I used to grind the teeth off, break in half and sharpen one end to make very good gasket scrapers. Quote Link to comment Share on other sites More sharing options...

pegasus bridge Posted November 11, 2014 Author Report Share Posted November 11, 2014 My dad got me an old industrial hss blade, it was about an inch and a qtr wide and 14" long, made a machete from a pattern I quite liked, hardwood handles, ground then with the angle grinder and finished them off with the dremmel type tool. I changed the point for a more traditional shape. Quote Link to comment Share on other sites More sharing options...
Paddy Galore! Posted December 1, 2014 Report Share Posted December 1, 2014 i made some very nice stiletto blades out of triangular and half round files when i worked in the foundry, it was very handy having some industrial grinders and belt linishers in the fettling shop. i'd then "burn" cast a handle on the end. they were stupendously sharp, and yes kent they did keep their edge.

figgy Posted December 23, 2014 Report Share Posted December 23, 2014 The big hacksaw blades are bi metal so after the teeth the metal is quite soft,the knack is to sharpen the first few mm of blade Quote Link to comment Share on other sites More sharing options...
