Hey Guys....
I as well don't like the idea of a half open blade in a sheath..
Theres no point to it..
If your going to do that, you may as well carry a fixed blade...
A deployment system on the other hand is completely another story in itself...
The Speed Dialer for the new Spyderco Waved Endura and Delica is in my opinion one of the best ways besides pocket carry for these particular knives...
The Speed Dialer teamed up with the Mercharness, allow many different types of draws while using the system.
You can read more about them here:
www.mnsi.net/~nbtnoel/speeddialers.htm
The Knives are held firmly in place, although allow for a crisp,clean and quick one handed deployment, from a strong arm, cross draw, left,right, both in forward and reverse grip.
The speed Dialer also allows the knife to be drawn quickly from a seated position, and will also carry IWB via a static line...
Please feel free to drop me a note if you have any questions...
BTW..
I also Agree with JGD..
Nothing Beats proper training...
