Anyone else have a 3V knife outperform their Busse?

SO your saying the heat treat affects how easily it rusts?

I dont understand that. Can you explain please?

I don't understand the whole story, but heat treatment has a huge effect on what elements end up in solution, and which ones form carbides. For instance, if you high temper stuff like 3V, Elmax, M390 etc it causes secondary carbide precipitation (more carbides such as chromium and vanadium carbides) which means less of these elements dissolved in solution. (The more carbides incidentally the less edge stability). While if you low temper more of it remains in solution as you don't reach have the secondary carbide precipitation, so more chromium is tied up with carbon to prevent rust.

Again, that's about as basic of a description as you can get, but you get the idea.

People often simplify metallurgy way to much. For instance the idea that softer blade is necessarily tougher is not true. Some steels (like O1 for instance) have embrittlement zones in the high 50's and are tougher at 60-61.

Thank you for the information! It makes more sense now.

Well put cash

Never been disappointed by my Fehrman knife, to the many I have loaned it to none of them have either. Never rusted, never had edge trouble. Mine is one of the first generation models so its been around since the first days. Thats a good history.

I can say the same with my old school Busse's. Every one has been a top performer.

Cant say much else.

I don't think you can leave Fowler off that list.

Leather I concur about fehrman..I have had a rust spot form on my gso 5 though but it was tiny and only surface rust.

Bos is legendary in these parts, well deserving of a spot, as well as Rowen, he does things with 1095 no one would have thought possible.

Agreed, and a caution to those interested in high carbon steels, avoid bead blast and anything that can hold moisture. Satin and polished surfaces are honestly best for them. The only way I've been able to avoid rust on even my INFI is to treat it heavily with a rust preventative. But its only temporary, high carbon firearms are in that same league. Not difficult but necessary.

I thought Bos did all of Striders heat treat, or did that change?

Bos taught them how to heat treat if I recall correctly, now Strider does there heat treat in house at least on there S30V blades.

I also agree with Rowen his 1095 is better than any other I have ever tried.

Agree with qualification: Strider = Paul Bos. Even though they're doing most of their heat treating in house now, he started them out and they still use his protocols

Hartsfield definitely broke important ground with differential heat treat on A2 -- certainly understood that steel better than many.

Have to add Phil Wilson to the list; no one knows more about heat treating high-vanadium/high-hardness CPM blades--or gets more performance out of the powder steels IMO.

Jerry Busse is still the King. Long live the King. :thumbup:


(Edited to add: Looks like several of us were posting at the same time about the Strider/Bos thing--obviously well known.)

 

[leatherman]

When Buck moved its facilities, Bos moved with them making it difficult for Strider to use him for heat treating, but like Isheldon said, he did teach them how to do it right.

Does Mr.Hossom do his own HT?

 

[Will York]

Does Mr.Hossom do his own HT?

He's always had Paul Bos do his heat treating--at least I've not heard of him changing.

 

[Jerry Hossom]

Nope, he hasn't changed. Paul's shop does my heat treating. It is especially important with 3V that it be done exactly right. Anything less is just not 3V.

Will, it's been too long, bud.

 

[Lycosa]

Thanks gang and thank you for adding other outstanding heat treaters.

I've been using Busse knives for quite some time. Nowadays I use my boss jack le almost daily in the kitchen not because it's great kitchen knife, but just for the pure fun of using it. I've never had any problems with rust on my infi blades. For some time I also use Fehrman knives. I also never had a rust problem on them. After some time of using the non coated Fehrman peace maker, I had some rust spots under the scales, but the rust was superficial. After using mentioned knives for some time in the kitchen, I noticed that 3V is more prone to catch a light patina than infi. But i never experienced pitting with my 3v Fehrmans. To tell the truth I don't care too much for my users - I don't clean and oil them daily, but I use one general rule - I never sheath a knife when the blade is wet. I always wipe the blade dry before sheathing it. Inside the sheath when the blade is wet, rust has perfect conditions to grow. I think that might be the reason this 3V gso blade rusted so bad.

Gotta love it when the pros drop in! Hello mr. Hossom..thanks for the info.

 

[Dan Keffeler]

I have been impressed with Nick Wheelers' HT of W2 and other steels. Brad Stallsmith at Peters' HT should be mentioned as well.

Hey Dan very nice to see you here bud!!
