154 Cm

Nobody mentioned D2 tool steel.

I have a couple of D2 blades and was wondering where this steel rates among all the others mentioned.

I believe some posts awhile back mentioned that it chips under impact.
Any views in relation to the other steels mentioned in this thread?
Thanks.

I think the original comparisons were among stainless varieties only. D2 is a near-stainless tool steel. I have noticed some slight chinks in my new Kershaw Outcast. :( I sure like it on my folders though.:)
Folks here have said that tempering is especially critical with D2 and have cited Dozier as the master in that arena. If you get it wet, or even moist, wipe it down quickly especially if you value the finish. It sure is pretty when it's finished right.;)

All of the above high carbon stainless behave in that way, little flexibility, now impact toughness, D2 tends to shatter though, break into multiple pieces.

What do you mean by this? Do you think Spyderco is the only company to use VG10?

Here is a list of the companies I know who use VG10:
- AG Russell
- Al Mar
- Beretta
- Browning
- Fallkniven
- Kershaw
- Knives of Alaska
- Seki-Cut
- Spyderco
- William Henry

I like VG10 better than S30V because it sharpens easier. In my testing it also kept a scary edge longer than S30V. In overall edge holding S30V is the best stainless I've ever tested.

Not to mention that Spyderco also uses S30V on some of there knives as my Para-Militaries blade says right on it, "CPM S30V". So why would Spyderco fan's automatically like VG-10 best Lil Timmy?
 
What do you think caused the manufacturers to abandon BG42 a couple of years ago, Cliff? I never understood why it didn't get more use in the industry. Even Chris Reeve switched to S30V and he did a really nice job with BG42.

Change sells. Plus BG-42 got hit with the one-two punch of Talonite / CPM's and never made significant headway.

The only manufacturer I know that used BG42 was Chris Reeve. I have a prototype Kershaw Avalanche with a BG42 blade, but it was never put into production.

Heat treating BG42 requires higher temperature and different stainless steel foil which is much more expensive than standard heat treat foil.

Another problem is dealing with Timken-Latrobe. When I talked to them about stocking their steel they didn't seem to be interested in knives. Compare Timken-Latrobe to Crucible. Crucible bends over backwards to help the knife community.

Now Crucible has released CPM 154CM. It is very close to BG42 and it is made using the particle metallurgy process which makes better steel. I have not used CPM 154CM but I look forward to comparing it to BG42.

SOG used BG42 for a couple knives.
 
Buck also made several models in BG42. Even Gerber had a model. In fact it appeared to be the oncoming fashionable steel until S30V came along. Sometimes I wish it had become the fashion. It must be due to the difficulty in dealing with the steel in a production environment. That's usually what does it.

The Buck's came and left so fast I never got one. I wish I had. I've thought about getting one from Pete's but I never did get around to it.

I didn't know Gerber ever used BG42. What was the name of the knife?

It simply never established the hype engine that S30V developed which pretty much smashed every other stainless pretty much out of existance. S90V is directly better for the vast majority of knives S30V is used for.

Origionally S30V was marketed in fact as a cheaper alternative, it was known to be a step down, but simply a less expensive alternative, give up performance for price.

That viewpoint has long been deleted and few custom makers have reduced prices since switching to S30V.

Cliff, have you actually seen D2 shatter into pieces and if so may I ask what knife it was?

Would a specific heat treatment employed on D2 reduce this characteristic?

Many thanks - I respect your opinions.

S90V is supposed to be VERY hard to resharpen, I think that's why most people prefer to use S30V instead.

Who marketed S30V this way? It was not Crucible. It was not any knifemaker I know.

The price difference between S30V & S90V is about 10%. In other words less than a dollar per knife. Cliff, do you remember the names of the knifemakers who did this? If you do not have data to back up your comments all you have done is use this forum to bad-mouth custom knifemakers.

You are correct, S90V is nasty to sharpen. However, it holds an edge for a very long time.

You have to give to get. ;)

I've found that S90V can't take as fine an edge as S30V. It always feels more coarse.
And about D2, that stuff is tough. My local competitor has a gladius made of through hardened D2 and it is a serious piece. On the end there are bits of another sword welded on to it. He also used it at fair to cut through CAS and Hanwei swords as demos. (He worked at a sword booth and would give people disscounts if they let him make a spectical of it.)
