Laminated blades don't give accurate readings, from what I understand. They can't be tested on the flats, since the cladding is covering any testable areas. Testing the exposed core is difficult, if not impossible, due to the angles.

I see. That must be why HAP 40 is missing. Thanks.

Has SPY27 been tested?

Anyone on the fence about SPY27 can get off the fence now. This is going to be some good stuff. SPY27 is to s30v what REX45 is to M4. Lower carbide volume, but higher hardness for equal or better wear resistance. Lower carbide volume and higher hardness = greater edge stability, and better sharpening response.

Get it while it's hot!

I'm new to the forums, but I've had a whole bunch tested by jcoolg19 on YouTube. 6 videos to be exact lol. Mostly spydercos but other knives as well. I need to re-watch them so I can post the results on here accurately. As well as screenshots of the actual videos for source verification.

Here are the results of 48 knives I had tested for Rockwell hardness. Some were poked once, some 3x but I'm listing the overall average in order of softest to the hardest. In my pocket there is a rex45 pm2 that tested 66 from previous owner. So 49 in total.
