I seem to recall watching a video a while back about Japanese bladesmiths profiling their blades on metal shears and was wondering if anyone else used them to profile their blades.

They used hydraulic sheers but manual shears such as this seem safer and reasonably priced.

I rarely work with anything thicker than 1/8" and this seems much faster than my bandsaw.

Does anyone have any thoughts either for or against using one?
 
I have a similar shear. Tried 1/8" 1084. Didn't work.

Mine works up tp 18 ga. non-ferous before it starts to wander. Teddy
 
I have one of those, but assumed that it would distort liner material more than a bandsaw so never tried it.
Mine is working pretty hard on 1/8" mild steel- probably not the tool for blade stock, though a hydraulic one might be great for production.
Good point about preheat, things shear pretty easy at a "black heat," 3-700 f. Not sure it'd be good for the shear, though.
 
So it sounds like you could use it right after you normalize your blades, then grind and HT.

I'm using 52100 and normalizing before shaping and grinding would help with decarb for sure.
 
I got a big 12" chear on sale from enco, 100$ shipped to my door! I have cut some thick stuff, mild steel mostly, but did cut some thin 15n20 no problem. I would recommend it.
