They claim it gives better feedback than our typical 300 series spring Stainless Steel that has seemingly dominated our hobby. Obviously the biggest drawback to the carbon steel is the rust factor, but with a black oxide coating...are they onto something?
I personally loved the way a thinly filed allen wrench felt in a lock. Feedback was awesome. Too bad it'll kills your grinding wheel AND fingers to make one pick.
I might have to give myself an early christmas gift and write a review
