ESEE Glassbreaker Attachment Idea [EDIT: Now With Prototype]

I have always thought it would be nice to be able to attach a glass breaker to the tang of an ESEE-4. Although I don't have the skills necessary for this, I pulled together my 3rd grade drawing skills and whipped a diagram up. What do you guys think?

EDIT:
The interest in my original idea had me itching to take it a little further. So, this afternoon, i crafted a prototype attachment. It's made out of recycled milk jug plastic (like that used in decks). The glassbreaker itself is nonfunctional and is for viewing purposes only.

here is the link to the album with pics of the proto.

it's rough, but it gets the idea across a little better. I would like to make it more profiled to the micarta, but the dremel was not cooperating with me towards the end. i'm open to any suggestions, criticisms, etc!

I am not a big fan of the glass breaker pommel except on the ESEE5 b/c of the weight the 5 packs ;helps in the breaking of the glass.
I prefer the modified pommel on my 3's and I like the pommel on the 4 & 6
 
I don't see why that couldn't work. Seems like it would be a fairly simple accessory to produce. (Though I'm not very knowledgeable of fabrication costs, issues, etc) One thought would be that the screw / bolt holding it together would have to be very strong to avoid shearing it on impact.

Also has anyone every attempted breaking glass with the regular pommel?
 
That could work if it slides in the middle, so its not resting just on one side, similar to those wrenches that i have no idea what they are called.

yeah that's what im thinking. (sorry didn't think to illustrate that in).

It's cool, but may need more than 1 attachment point, or it could pivot when striking... best bet would be to have something that goes under the scales and has a longer "shank" to it so it's secured and not able to move with a glancing blow to the surface you're striking.

true, but wouldn't it give it a considerable amount of strength if it were made to be flush with the micarta of the handle scales? That way it would not only prevent pivoting, but the force of an impact would be spread throughout a larger area, putting less stress on the attachment point?

I'm no physics wizard, so if i'm wrong with that, tell me haha

That looks great, may not have to worrie about glancing blows if it's almost like a full cap or the idea where the second screw hole would share the Handel hole
 
I think as long as you make it mount in double shear with a grade 8 bolt, and mount it flush with the micarta, it will work great.

Possibly, but not if the attachment saddled the knife and was fit to the shape of the original pommel, like I think he is describing. Of course, this would make it rather thick. A bolt with a shank long enough to traverse through the knife and each leg (just enough thread for the nut) would maximize strength. having one thru-hole and one threaded hole on the attachment would probably be best though.
Storage when not in use?
Cool idea, innovative idea, nonetheless!

AMEN to this!!

However, I can also see myself buying one to have "just in case" my only question is whether the cost of production would be worth it because I doubt most people who purchase knives have the need for a glass breaker and other than us ESEE addicts would the return on the investment be worth it?
 
I think it's just a damn good idea. That's the reason we love this forum so much. Some great ideas have been generated here. Shon, Mike and I are going to discuss this at SHOT and see which way we go. If we do it, then the OP will get a royalty on every one we sell.

Phyx: email me your mailing address. Would like to send you an Izuila or Izula-II (our choice) for displaying some great thinking power on this forum! jeff@eseeknives.com
 
My thinking is making this so it can be slipped on quickly for emergency use.

That make no sense...you might as well carry any glass breaker in that case. I think Phyx original screw atachment is the way to go...ooh, i just questioned the MAN
 
But honestly, Tom, how many people will actually attach and keep this on their knife? What if it was two ways. Slip on and permament attach in the same package?

The times I've had to get someone out of a vehicle by breaking glass, I could have easily picked up the breaker from the ash tray and slipped it on the knife. True I should just carry a regular breaker so maybe the whole idea is only good for those who want to permanently attach it. In that case, I would never buy one.

And....the MAN needs to be questioned every so often! Especially since this will be your baby to design should we take on such a project. We just sit back, look cool and play with crazy women. You have to do all the work! Now get back to work on our new high dollar fire kit you're designing! We've got CNC lathes itching to make chips!
