Interesting read

Thank you for bringing this article to our attention.

We read through this article and were amazed Thomas. This was really a comprehensive attempt  to discern  differences/advantages of different knife steels.  Our hats are off to CATRA and Knife Steel Nerds for undertaking this study. Studies like this are how speculation and anecdotal evidence eventually get put to bed and fact rises in their place.  Does one study mean the issue has been forever settled? Probably not but it is most certainly a step forward in the process.

You're never going to satisfy everyone's questions with a single test process and we, of course, are left unsatisfied to some degree with this one. There was no edge sharpness information gathered either pre or post testing. Why it was not, we do not know, but obviously the producers of the test had their reasons. We see that the tests produced, in one sample, 20 - 23 micron wide edge apexes. In the pictures provided, the apexes of three knives are obviously ground (or smashed) flat. Any of these edges would have, long before, exceeded the upper limit of the BESS scale. We understand that the purpose of the test was to gauge the wearability factors of one steel versus another but wish that the test had been more attuned to usable edges. Like we said, you're never going to make everyone happy and this small criticism is dwarfed by our appreciation of the volume of work produced by Knife Steel Nerds. 

Three cheers for Knife Steel Nerds and CATRA and thank you Thomas for letting us know about this study!

We have a lot of knowledge here - and we can use our knowledge to control and test what we read Smile

I hope you all have read the link above, then gone to "home" and read other reports...

This one is very good in my mind and experiance:

Appreciate that Thomas, and great to know about Larrin - I wonder if he is the same Larrin who recently joined our BESS forum.

The data on edge angle obtained by Larrin in CATRA testing of the wear-resistant steel is immaculately in line with the SET testing of mainstream steels, and these two are mutually complementing.

I believe there is only one me thus far.

Ha!

Welcome Larrin! I am happy to se you here Smile

Well isn't it a small world! After composing our post congratulating Knife Steel Nerds on their steel study here on the BESS Exchange we bounced back to the Knife Steel Nerds blog and posted our congratulations there. We hadn't connected Knife Steel Nerds to Larrin at the time. Now, thanks to our members, we have made the connection so very happy to recognize Larrin as a member of the Bess Exchange.

You would be very much welcome, Larrin, to promote both your studies and your blog here on the BESS Exchange if you feel that it would be to your benefit.

And by the way KG, we see that you are back. Would you be kind enough to have a look at our thread http://bessex.com/forum/showthread.php?tid=331 Edge Straightening Tools where we posed a question for you?
Would be much appreciated.
