Cut 1018 steel 9/16" diameter bar

[Alpha Knife Supply]

Please provide links/refs, thanks.

I was at a hammer-in where Bob Kramer cut allthread with a 52100 chefs knife. I think the allthread was .375" diameter.

Bluntcut: The blade might have failed paper cutting, but it sure did cut the rod. Good work.

BTW, your webpage link seems to be broken - for me at least.

3/8" diameter bolt is quite large (9.5 mm) and of course, impressive! This article: https://www.newyorker.com/magazine/2008/11/24/sharper did mentioned cut through a bolt. It would be really cool to see a video of it and more importantly knowing the edge geometry...

Thanks Ken! I just received a part to build a setup for cutting mild steel rod with some level of repeatability. I re-sharpened this edge to 20dps to test against 9/16" dia rod.
The sig's link is dead because I stop the web-service for the too-out-of-date-to-live website. Well, I will remove the link. Thanks for noticing.
