: A while ago a friend of mine told me about cryogenic treating. He races

: I am an arborist and own a brush chipper. If you are unfamiliar with the machines, here are a couple of links:

: Last week I bought a chipper from a friend and got three extra sets of
: knives. I am considering running a test on treated and raw knives to
: see what service I can expect. While at industry trade shows I have
: talked with a couple of the knife manufacturers to see if they would
: advise cryo treating. None of the sales reps could answer whether it was
: advised or not. My suspicion is that, since they are in the business of
: selling knives at a similar price-point as other manufacturers, they
: would not be willing to invest the extra money in the treatment.
: Do you have any experience with brush chipper knives? Since the material
: that I chip is not uniform and the chipper disk is moving so fast, I am
: concerned with a knife fracturing. Please let me know your thoughts on
: the use of cryo treatment for my knives.
