I've been working on this idea for a while now, and I'm glad to say I finally have a working prototype in my hands! I'm sure a few very minor changes will occur after more testing, but overall I am very happy with the results.
The sheath system is shown here on one of my EDC fixed blades I've had around for a while, but I am sure it will work for many knives. I'll be using it quite a bit in the future!

The retention device is an added level of security- the sheath still has a tight molded fit and can be carried securely without using the device- or "safety off" if you will. The retention device is adjustable for tension using the chicago screw (please excuse the beat- up one in the prototype!) and will be available in different colors as well.The exact shape of the safety will likely change on some future models as needed.

The safety device itself is a solid piece of G-10 composite, fitted with a press- fit steel pin and pivoting on a chicago screw or similar device. It is hand molded and fitted to the sheath for a secure fit that clicks into place.

How it works:
1: Grasp the sheathed knife by the grip.

2: Push the device out of the detent and away from the blade with your index finger.

3: With the safety out of the blade path, retract the blade from the sheath as normal.After re- sheathing the blade, snap the safety back on...

...Or carry with the "safety off" if extra retention is not desired.

Thanks for looking, and feel free to let me know what you think!
 
Thanks guys! I'm not sure how I'm going to market this quite yet, but I think it will be on a lot of my Kydex sheaths from now on at least. I'm also working on a modified version with an extended spur that is quicker to operate under stress. I may take my design logbook and go talk to a friend of mine at a lawfirm to see if it's worth looking into a patent as well.
 
I think its defiantly worth looking into a patent for it, and to make sure someone doesn't already have a patent on something close enough to claim infringement. If its all good patent that sucker, I think you have a winner there

Very neat. As far as patents, Jay Fisher has been doing something kinda like it for a while, though not exact. There's also a Kydex holster company (can't recall the name right off) that uses something very similar, so you may wanna check around first.
 
Thanks for the info! I will be doing a lot of research on this one for patent or design conflicts in the near future before proceeding too far. I've looked at Mr. Fisher's sheath lock- which is in my opinion WAY better than what I've come up with, and quite a bit different. That is a well thought out mechanism which I have no doubt has much better retention than my design, although with luck mine will still find its place somewhere. All you can do with an idea is give it a try and see what happens!
