Mainly in corrosion resistance. That said, 13.5% chromium is very stainless. There might be a slight toughness/edge retention difference but I truly don't think many would notice this. I sure wouldn't but that doesn't say much.Pockets wrote:Does 440C count as both an upgrade and a budget steel?
Wow! I would be super stoked to see Byrd Knives in BD1 !sal wrote:Hi Nick,
Timely question. Perhaps some history?
When we began working with Carpenter several years ago, I was working with Rick G. (now we're working with Jim M.) Great guys to work with. As we were helping to develop knife steels with Carpenter and testing them in our lab, Rick asked if there was something they could do for us? I asked for and got CTS-BD1. I wanted an American steel with the approximate chemistry of Gingami 1. We had plans to use it in our US plant for the more cost conscious models. We were using more and more expensive exotics and felt that we needed a good American made hard working ingot steel with good corrosion resistance. We also wanted to use an American steel in our China made models. We told them that if they made a good steel and we were using it in our Chinese models, others making knives in CHina would be encouraged to do the same. US exports of steel to China is a good thing and the knife industry gets a very good steel.
Carpenter invested a ton of time, energy and money to create the steel and Ron L. from Carpenter has been going back and forth to China setting up inventory and teaching makers to use the steel. Eric and I will be meeting with makers in a couple of weeks to begin BD1 useage.
I've been using a Chinese processed BD1 Mule for the past week in the kitchen, cardboard and carving. 58/59 and performing well. We'll keep you posted.
The 8Cr13MoV knives are badged 440 by Boker. Schrade labels the 9Cr13MoV EL-08 as 440C. I think it's more a case of American onsellers just slapping a "near enough" label on them. The heat treatment might not be what it could be.Tally-ho wrote:9Cr13MoV is stamped / engraved on the tang of the blade, yes, but the cutting edge retention is pretty short, so there is a great probability that the steel that is used is not what it is claimed to be, or if it really is 9Cr13MoV steel, its heat treatment is poorly done.
The chinese 9Cr18Mov steel’s composition is the closest (but not equal) to 440C, but some Enlan knives rebranded by Böker (for the Böker Magnum line) are described to be 440 steel on Böker's website.
I did read somewhere that Chinese manufacturers go for a relatively soft heat treatment, something to do with prolonging machinery life in subsequent machining. From abuse videos I've seen on YouTube, the Inrons do seem to have made a greater effort though. Odd.The cutting edge retention of the Enlan and Inron knives I tested are way under the 440C steel of the Böker Plus knives.
Navy knives are claimed by the manufacturer to be made with 440C steel but Puma which sell some exact same Navy knives rebranded under the Puma-tec line, are described to be 420 steel. Who's right, who's wrong ?
(N.B.: Puma is a reputable German manufacturer. I tend to trust this manufacturer, prior to any Chinese brand).
Almost every country has a high carbon equivalent of 1060, 1075, 1095, etc. Also spring steels for axles.Donut wrote:I was thinking about this and wondering: Does China manufacturer any good carbon steel/non stainless steels?
I'm with you. It should be cheap to produce too.Donut wrote:1095 or 1060 sounds really good. I am thinking they would have to be sprints. I haven't seen a Byrd sprint yet, but Tenacious sounds great and would be an awesome candidate for a carbon steel.
Yea, and ESEE but those start at $75 for a fixed blade without a handle.Donut wrote:Apparently you and I are the only ones who think so.
-er, me, by way of Tyrion LannisterI drink, and I cut things.
