Eric, Are the Wakis differentially heat treated or spring tempered

I was reading Steelnut's thread and , he says, the new Blade ad says the Wakis are spring tempered. I was was almost positive they were supposed to be differentially heat treated. Eric, can you fill me in with the correct info? Thanks.


Hope you had a great Knob.:thumbup:

Steel SR101 Differentially Treated
 
Differential temper and spring temper are not mutually exclusive. A differentially tempered blade would typically have a softer, "spring" tempered spine and a harder edge.
 
Thanks Mustard, you have great taste in knives. :thumbup: I just wanted to hear from Eric what I really have. Thanks again for your help.

True, but folks have been noticing that stripped Wakis do not show the temper line that is readily evident in the other SR blades with differential tempering. Thus the questions.

When I think of 'spring tempered' it brings to mind steel that is flexible but lower in hardness. Great for the back of a blade to enhance the shock resistance, but not something you want for the edge. A throwing knife might be spring tempered, but you don't care if it has any edge holding.
 
The Waki user of mine sure seems to hold an edge.

I did what they did in the testing video (just the tree...not the vise test...) many times. It could stand a touch up, but it still slices paper...just like the video.

Sure flexes too.

Awesome blade. I just wonder how it does not have a hamon. Is it like those gradual bifocal glasses? A gradual transition?
 
As alluded to by Tripton, I do not honestly care what process was used as long as it displays the performance of the ones shown in the video. It is an awesome product either way. I am curious as to what process was used though as, as was said above, different processes were claimed in different communications.
 
I am also really liking the Semi-custom nature of the one I own. It was delivered with my choice of blade color, handle material, and handle color combination. That goes a long way in my book to making me feel like it was made just for me. It doesn't hurt that it seems few others ordered a similar combo.
 
lack of a visible hamon doesn't indicate lack of a differential temper. The transition between the two could be gradual, or the hamon could simply not be visible. It sometimes takes a bit of work to get a hamon to come out and be visible...


Seems like someone needs to volunteer to acid etch his waki to see if a temper line shows up :D :thumbup:

I don't think they really were - I just think one chose to highlight one feature of the other. To us, who are familiar with SR-101 and its properties and history, they pointed out that it's a differential temper, with a spring tempered spine and harder edge, while for the magazine ad, for the sake of simplicity, they simply pointed out the spring temper, which indicates the toughness of the blade and ability to flex.


I see no contradiction or different process claimed - just a choice to emphasize a different feature of the tempering process.
 
Ok, I do not disagree with you but outwardly it does look like they are describing different processes though both may have taken place. Clarification from Swamp Rat would be nice, but again only for curiosity sake on my part.
 
Would be cool if the first run was differential and the second wave is "spring":thumbup::cool:
 
The edge is approx 58 - 60 RC. . . The body of the sword is spring tempered at around 48 - 52 RC.

It is differential because the two hardnesses are different. . .

Hope this helps clarify the issue

:D:D
