Geez... we need to get Jim a bionic arm or something!
This thing is the closest to WC-Co you can get in steel...
I am very glad it performed well at 15-dps in the full review as well :thumbup: The 0.018" BET makes it suitable for a lot of other utility-purposes, but I can imagine that it was annoying for Jim pushing an edge that much thicker through all the cardboard
I'd be afraid that this steel taken down to 0.005" would fracture
massively if the edge ever bound-up in something, given how like it is to cemented carbide...
Another thing i wonder - Maxamet's likeness to WC-Co also lends it to very hot working hardness, i.e. it doesn't lose its temper easily. From the datasheet:

It is important to recognize that the carpenter test uses 1000'F/500'C specifically because a number of studies have shown this to be ABOVE the maximum temperature transferred to the cutting tool or work-piece during typical power-grinding
dry (no coolant or lubrication). I have many times questioned assertions that power-sharpening (which isn't generally capable of getting anywhere even close to 500'C) necessarily generates sufficient heat to affect edge-temper - particularly since that would mean that cutting alot of cardboard would have the same affect - but here is a case where it wouldn't even matter
