Re: where is Cliff Stamp?
One more thing. Cliff, whenever you get around to doing a write up on the Maxamet mule I will be eager to read your observations. I have a few other things I have to do first, I have a knife in 304 stainless for example which is an ideal benchmark, and a 1084 custom hardened knife to be compared to...

Re: where is Cliff Stamp?
Finally, Cliff has taken a ton of flak for his use of the word "shill." I tend to think the term is too loaded and that he shouldn't use it.... I agree, which is why I stopped using it. I would argue it technically correct, but regardless it simply is taken so much as a pejorative it simp...

Re: where is Cliff Stamp?
The gist of everything I've been reading seems to be that minimizing grain size is universally beneficial, and shrinking grain size further is a subject worth pursuing. There are a few issues with grain size minimization in the extreme : -loss of hardenability results quite dramatically -the HT pro...

Re: where is Cliff Stamp?
I really want to know how those s90v chopping knives perform. One of them has a HT that you should really not use on that kind of knife. In ideal circumstances it will be 62/63 HRC, have a very high secondary carbide distribution, full martensite and very strong secondary hardening. This produces v...

Re: where is Cliff Stamp?
Awhile ago I started volunteering more which drastically reduced the free time I have for hobbies. I generally can spend between 1-2 hours a day answering questions about various things on line and I have to do a kind of triage in picking where to respond since my time was so restricted. I try to fi...

Re: ZDP-189 - choosing the right waterstone
Now you have established the parameters for discussion, deliberation, and decision. I design knives all the time, for example right now I have two custom knives being made in S90V (stock 2.25 x 13.5 and 0.260" and 0.290") : -partial tang -edge is 0.025" before bevel -full height grin...

Re: ZDP-189 - choosing the right waterstone
I am thinking it would have at least a handle and a blade and the steel will contain a significant amount of iron.N. Brian Huegel wrote: So what type of knife would you design with Spyderco?

Re: Diamond vs CBN rods grit
Whatever happened to Cliff [...] I took on a volunteer position which I thought would be ~10 hours per week, it has multiplied so my free time is severely reduced. I tend to focus the time I have (internet wise) in answering questions people ask me directly. My activity even on the forum I run is p...

Re: ZDP-189 - choosing the right waterstone
The version I have is the two sided 1000/6000 combo, I love the King 1000, but as mentioned before, IMO the utility of the 6000 is limited. These get sold as a refine/finish combo for woodworking tools, but the truth is that the 6000 side isn't particularly good at that job either, even with traili...

Re: ZDP-189 - choosing the right waterstone
A course DMT is likely too big of a jump for the Aotoshi without a lot of work. Could you do it, sure, but the number of passes would be vastly reduced with an intermediate. The DMT fine won't really resolve the major problem which is the burr/over grind of the apex. A King 1000 or similar would be ...

Re: ZDP-189 - choosing the right waterstone
Of all the water stones I own the King 6000 is probably my least liked, it's very soft and has never delivered an edge that I was satisfied with... and I have given it many tries ans used different techniques with it. One of the most unfortunate things about stones is the lack of discussion of the ...

Re: ZDP-189 - choosing the right waterstone
Cliff, if you are still watching this thread, what is the biggest grit jump you would do from the 400 SS when applying a microbevel? It sounds like the Spyderco fines aren't an issue, which makes me think the 8000 glasstones might be able to apply the microbevel without any problems. That would be ...

Re: AEB-L -steel, my new favorite
I wonder where the information came from that AEB-L has no chromium carbides? It would be easily possible to harden it in such a manner, you likely would not like it however because of the difficulties with very high levels of retained austenite and loss of hardness/strength/toughness. AEB-L is an ...

Re: Sharpmaker and Mineral Oil?
The stones are solid, they won't significantly absorb the oil. As to why you use lubricant, it is because properly applied, it enhances cutting, and minimizes degradation of the abrasive hence why lubricants are so common in industry. As with anything you can do it improperly. The level of lubricati...

Re: Un-sharpened blade heel, what do you think?
There is no need for sharpening notches to snag, they can be just sloped forward. However the knife can also be reground fully sharpened right back to the full stock. There are a few guys on YT who do this as part of their typical sharpening services. Once it it fully sharpened it tends to stay that...

Re: Corundum: Wonder Material
Phase refers to a way the structure is aligned. For example steel in general is a mix of : -martensite -austenite -cementite + alloy carbides There are other phases (bainite/pearlite) but they are usually minor in hardened steel. When a knife is subjected to impact then the austenite can absorb the ...

Payne, do you have any ATS-34 knives, 154CM, S30V? I would be curious how you see VG-10 compared to them in regards to corrosion resistance.

I'll chime in- there's some 'purists' in aviation that prefer not refer to H1 as a 'true steel' due to the nitrogen content.....We can argue the correctness of it, but I've encountered it also (resulting in a raised eyebrow from me). Nitrogen has been discussed in steel as far back as 1880 (Allen),...

Re: Corrosion resistance on VG-10
I am not sure of the question. When steel "stains" that is actually oxidization, i.e., rust. It is just a different type of rust as it can form in many different ways. Strong acids will tend to form a black oxide (normally called a patina or staining), very weak acids will form the red oxi...
