Review on Starrett 117C Center Tapered Diameter by Ben Jacobson

I bought this and used it on regular cold rolled and even hot rolled steel for a couple of months and it worked fine. It didn't break off, the tip stayed intact and was a pretty good hit overall. A light tap on 304 stainless steel instantly twisted the tip, rendering it virtually useless. For the price I think it's amazing, especially from a well known brand like Starrett, but the tip rolling straight away on stainless steel was quite disappointing.
