Ti blade ????

Don't have the actual text either. It might be an update to 12020 but I would not swear to it.

But when I read through it, I do not remember any "grandfather" clause built into it. If there is not such clause (subsection) then it would ban all non-detectables. How would an officer determine the date of manufacture anyhow.

I know that when they updated the dirk and dagger diff. in 12020 it was retro active.

But this law is the least of all the reasons to hate CA. There are just too many other reasons to hate the state.
 
If Ti can now be detected, shouldn't it be legal there? Not that I expect common sense from the California government...


I actually gave my extra Ti Woo to a friend who moved to CA for a year. He used it as his EDC.
 
CA will play to the lowest common denominator. So long as there is one detector that can not pick it up they will still outlaw it.

We are the home of the most liberal courts in the nation, after all.

Here is a link that shows the comparative qualities of Ti vs LM1.

Using cast alloys, which of course are not what the better stainless and Ti alloys are used in cutlery. Heat treated Ti is within 10% of the 250 kpsi, and properly hardened stainless steels can go well over 300 kpsi .

The advantages that heat treated Ti has would be in regards to ductility and impact toughness where it is far superior to the Cobalt alloys and the Liquid Metal ones (of similar hardness) .

Of course you can set high impact steels that are tougher and more ductilie than the better cutlery Ti alloys. A L6 or differentially tempered 5160 blade would be overall far more durable than Missions Ti, except for corrosion resistance effects.

The edge retention of Ti is low in most respects because of the low RC (~48), this can be dealt with by using a very coarse finish on the blades, and an effective serration pattern. So they are not good choices for those who want good edge holding with a crisp polished edge, neither are the cobat alloys for similar reasons.

Ti also has the downside of clogging ceramic hone rather badly, and induce adhesive wear on steels. I didn't notice similar problems with the Cobalt alloy blades I used.


Ti doesn't make decent light use knives for the above reasons, as a hard steel is usually far better, but they do make a nice heavy use knife if chopping is a critical factor (Ti is too light), and you need a lot of corrosion resistance. It might be an interesting large brush machete type blade due to the low density but the low hardness would be an issue on hardwoods.

I like to try new things, and I don't like to make comments on stuff until I've actually used the tool in the real world. So it is with Ti knives.

Several years ago, Benchmade offered a 970ST, a CQC7 with a titanium blade. The actual cutting edge was a strip of some type of carbide.

At that time, I was also about to end my love affair with chisel grinds; some I could get sharp, some I couldn't and none of them cut like I needed. But a titanium knife seemed like such a good idea I tried longer with the project.

I still have the knife; I traded it to a collector friend. He left it in the box. I thought I try again, and he traded it back. I soon remembered why I got rid of it.

I still have it in the box with a flawless polished edge from the Edge Pro. It drags as it cuts, and it pulls to the right. My friends who are into serious collecting all pass on a buy or a trade.

I'll probably die with this knife. I'm thinking of donating it to a soldier still in the sand out there, or a SEAL who likes chisel grinds and swims with knives. I'll take the tax loss.
