Emerson Wave Fans: Emerson Patent and more

[SpyderEdgeForever]

For fellow fans of the Emerson Wave Opener, here is the official US Patent:

http://www.google.com/patents/US5878500" target="_blank

" US 5878500 A
Abstract
A folding knife that is self opening when removed from a container such as a holster or pocket. The knife includes a handle and a knife blade with the blade hinged to the handle for folding from an extended, use, position to a stored position in a slot in the handle. A pin is formed on the knife blade adjacent to the hinged end, extending away from the blade when the blade is folded. When the knife is pulled from a container, the pin will snag the container just before the knife is fully removed, causing the blade to unfold to the use position. Preferably, the pin is hook-shaped with an end extending along the blade towards the blade tip. A releasable locking arrangement to lock the blade against folding while in use and for releasing the blade when desired for folding is preferably included.

I like the Spyderco Emerson wave Endura and Delica: They are two of the best Spyderco knives in my opinion.

I also mentioned in another post that I would try to find the US patent for the laminated titanium-carbon steel knife blades: here it is:

" Titanium-steel laminate knife
US 5256496 A
Abstract
A titanium-high carbon steel laminate composed of two outer layers of titanium with the steel in the middle. The steel being heat-treatable to very high hardness and the outer titanium layers providing strength and corrosion resistance. The laminate is bonded together by a brazing process. The brazing or filler material may be of various compositions. This laminate is invented for the purpose of knife and similar cutting tool manufacture.

Question for Sal or anyone: Please take a look at the titanium-steel laminate, and tell me what you think of it, as far as its ups and down sides go, for production knives. Would this make a good folder or fixed blade?

Ti lamination is very interesting! I looks forward to hearing more about it

The titanium lamination will be lighter weight than an all-steel sandwich of the same thickness. Depending on the cladding alloy, the steel sides might be stronger than titanium.
