Re: HRC Database
would love to see someone poke a SpyOpera, I've heard horror stories about Lionsteel's heat treatment...
Lightly insane.

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.

Re: HRC Database
One of my test videos on kurts channel. Sorry I'm not tech savvy on how to link videos.

Re: HRC Database
I just got a Delica k390. The results were a bit surprising. It was poked twice, with the results of 66.4 and 66.5 HRC
Re: HRC Database
Wow! That's significantly harder than other k390 Spyderco has put out. I'm curious to see how people like it.

Re: HRC Database
66 HRC, that’s tempting. I thought I was done.
Re: HRC Database
I am also curious. If these results are accurate, it makes me wonder about the heat treatment and toughness. I believe the previous K390 results were about 65 HRC, which is more in-line with Bohler data sheet.
Re: HRC Database
I will definitely be using and testing it this week. I may have one of the other guys re check it to make sure.I have had 2 different police 4s and one was right at 66 and the other 64.2. Most of the Police 4s were right in the 65 range from what I have seen. The PM2 I had in k390 was 63 something, which seems to be standard for that batch.
Re: HRC Database
The Manix 2 Xl dlc in M4 was tested as well. 2 hits both at 63.3.

Bump. I think this is important information.The Meat man wrote: ↑Sat Jan 11, 2020 9:03 pm
Don't know how I forgot Larrin's excellent article on H-1. In the article he had a Spyderco Salt measured and found it to vary from about 55-57 HRC. Might want to add that to the list.
From Larrin's website:
https://knifesteelnerds.com/2019/06/24/ ... -it-works/I was sent an analysis of H1 in a Spyderco Salt by Sandvik. They did not find an increase in hardness at the edge, in fact they found a decrease. The plot below is what I was sent, where the value at about 55 Rc was 0.4 mm (0.16″) from the edge. Unfortunately I was not provided an x-asis to see the distances between the measurements. However, the ~57 Rc of the steel is comparable to the value reported above from Crucible.

Re: HRC Database
This is an excellent effort, but I do not think that it is up to date. Is the current up to date spreadsheet?

Re: HRC Database
That's the 'official' spreadsheet for the group centered around the HRC testing efforts of Kurt (jcoolG19). The table is periodically updated, but the spreadsheet lags behind the testing by some number of months. I'm not sure, but I think LTK may maintain the spreadsheet.Naperville wrote: ↑Wed Sep 16, 2020 7:40 pmThis is an excellent effort, but I do not think that it is up to date.

Re: HRC Database

Re: HRC Database
I plan on getting the k390 endura when it is released. I may get the k390 endela as well. I am going to test everything I get now, so I will keep posting them as I get them.Cambertree wrote: ↑Wed Sep 30, 2020 12:06 amGood stuff. :cool:
Are you getting any readings for the rest of the current K390 Seki series, besides the Delica?

It would be interesting to eventually have data points for the whole array of different sized blades in a Seki release in a single steel grade. I wonder if there is much difference between the smaller blades like the Manbug and Dragonfly, compared to, say, the Endura, Stretch and Police?
