I'm more than a little stoked over this thing. Does anyone know what the handle material is? Aluminum, synthetic or what? Didn't say on the Gerber home page.

It is a metal handle. I certainly wanted one but I have several problems which keep me from throwing down for one. If it had been 3V or M390, I think I would have moved Heaven and Earth to own one.

I was going to buy one but:
- I would have rather preferred it had a fully visible full tang, not a cut down tang
- expecting a call from Winkler on a $450 Recon knife so quite a bit of my expenses are tied up this month
- S60V was rapped over on the Spyderco site. Here is what they had to say:

Spyderco was the first production company to use Crucibles particle metallurgy in production knives. I personally went to Crucible with crew to begin the project in the mid 90's. We began with S60V while is was still being called CPM 440V. We had no problem getting it hard, but in a hi 50's to low 60's it was so brittle that it would crack if dropped on concrete. We continue to experiment until we reached the conclusion that 55/56 worked best for the steel in knife blades. In the end, we dropped it. It was too hard to sharpen for customers, though edge retention was good. I don't think we would use it again.

440V discussion Wayne Goddard wrote an article I think for Blade magazine on 440V and introduced it . Like Sal this is the first PM grade I used. The idea that it had a low potential hardness probably came from me since at the time I was sending it out for heat treat and it came back in the 57 range. I was limited to about 1950 f. on my furnace and it really needed 2000 plus. Later I built a new furnace that would go to 22200 and did manage some blades up in the RC 60 range. At about that time 420V (CPM S90V ) came out and it was introduced as an up grade for 440V so 440v just kind of faded away. I have not tried the new introduction but hope to get around to it.

Yes CPM S90V came out before CPM S30V. Problem was that S90v req'd a furnace that would go to 2100 or so and most custom guys did not have the equipment to heat treat it. It has excellent wear resistance and that makes for good edge holding but the other side of the coin is it is hard to grind and finish. At the same time Chris Reeves was looking for a an up grade steel for his work and asked Crucible to come up with something that still had vanadium carbides for wear, had a CPM base, but would be easier to work with. CPM S30V was born and later since Chris had requested it became a steel "developed for knife blades" . I got a sample to try in that time frame and made a few knives with it and wrote an article about it. Also during that time Spydeco was also looking at it and the history on that is better told by Sal. Now CPM S90V has been gradually tweaked and the learning curve for heat treat and grinding S90v has made it possible for it to be used over a wider range of makers. Phil

Well, I guess we can only hope they've done their homework and made sure to have it heat treated properly.
That being said, I have of course had stuff from Gerber crack on me before. o_O:
