About 3 years ago, a vendor tested 5 sets of my knife-steels v-notched specimens. It was quite obvious, results were very low and force spread within 3 ft-lbs range. So I asked that vendor to perform unnotched specimen in the future - got a 'yes'. Since last week, that vendor is unwilling and I couldn't find any other vendor offer/willing to perform unnotched knife-steels. I can't even find - 3mm radius c-notch testing service for high strength (knife) steel either.
I would like to test 2 set of 1095 specimens, 58.5rc and 60rc. Plan for next 2 months, 1 to 2 sets per steel [ 1095, 8670, 52100, w2,440c].
Suggestion/idea on unnotch charpy testing services? btw - I'd pm

Alternatively, I'm starting to think about building a free fall impactor (4 lbs carbide hammer, 6 ft distance => 24 ft-lbs, increase mass if needed higher impact force). Result would then linear translate to standard 10mm thick. Thoughts?
