The "Ask Nathan a Question" Thread

This one will probably be quick, but we are producing 800 Basic Fives this year and those will be slow sales.

Has there been any consideration on making a portion of these "basic five-inch field knives" into a signature series version?
Much like the basic SDFK & the signature series SDFK. Even if it is a 100 or 200 out of the 800, I'm sure many people would be ecstatic to have a signature series with a swedge, thumb ramp jimping, and slight skeletonization.

Thanks
 
Hi Nathan the Machinist Nathan the Machinist

Did you finish 3V DEK 3 heat treat? I was wondering about your findings about the performance of 3V for heat treating more than optimal hardness.

I do not have an order in 3V (mine would be in MC) but I am wondering about the performance of 3V at 61.5-62 HRC. More than one source I was reading says the toughness of 3V goes pretty much downhill after 60-60.5. I mean it is known that the hardness and toughness is negatively correlated but those sources says that 3V takes a deep nose dive once the hardness passes 60.5. Since you are working exclusively with 3V, what is your observations about edge stability and impact toughness of 3V at different hardnesses between 60-62? Knifesteelnerds website shows that while some steel's toughnesses are relatively less affected by the increase toughness (e.g. MC), others steels (e.g. 3V) are overtaken by seemingly less tough steels at certain hardnesses (e.g. Cruwear overtaking 3V at 61-62).

Not Nathan, but he's written a lot about the D3V treatment over the years. A good place to start is the 'miscellaneous' section of the encyclopedia

Thanks for the link, I have briefly looked there but could not see the answer. I was not expecting to anyway. The question is quite specific and I do not think it would get discussed unless asked specifically. Such discussion would not mean much before as 3V in CPK is heat treated to optimal hardness for that steel which is around 60.5. I think it is the first time with DEK3 the 3V will be heat treated up to 62 in CPK. Also, since DEK3 would be quite thin, discussing this issue is more pressing.

The hard(er)/thin(er) FK2 iteration is stated at 62 HRC so DEK3 is not the first CPK in CPM-3V with the Delta HT at 62 Rockwell.

Mat beat me to it... 😀

Was going to say the same thing and add this: Screenshot_20230310_203515_Chrome.jpg

I asked this question before and I believe Nathan said it was a possibility. I REAAAAALLLLYYY hope this happens as it makes a ton of sense. A signature version with all of the scale options like ECAM, Vintage Westinghouse, Terotuf, Double Red and Double Black Canvas, Burlap, etc would be amazing. The BFK is an amazing knife and a signature version would be icing on the cake!

Only will make sense if it will have a swedge and some holes in the tang, and loose a little weight, too ! 🥰
