ESEE Glassbreaker Attachment Idea [EDIT: Now With Prototype]

Knife Dude said:
Just a question, wouldn't the tip of the knife also work to brake the window? Just in an emergency situation.. wouldn't mind to dull or brake the knife to safe someone from a car. Plus your hand would be further away from the shattered glass. Has anyone ever tried that? I am asking because I often have my 3 with a round pommel with me and it would be good to know if this would work..

Maybe, but I guarantee it's an easy way to slice your hand open. If it doesn't break the glass then with as much force as you'll be putting into the blow it's very easy for your hand to slide down the blade. Also because there is less length between the impact point and your hand you will control deflection better on the pommel.
 
I like the idea of a user installable/replacible glass breaker. I'd keep the breaker in a pouch on my knives sheath and install when needed. I probably won't by an Esee 3 folder, but this I would. :)

PS: to the people that prefer the rounded pommel, that's why this would be an attachment. No one's making you buy/attach it. But, to those of you that are questioning the usefulness of a glassbreaker, grab your ESEE knife with a rounded pommel, go out to your car, and do everything you can to break a window. For most of you, the best you'll do is scratch the window... and hurt your hand.

I Have used my 3mil and it did not break glass with it... If it was a dire situation I'd use the actual point of the blade.
I keep the ESEE5 in my vehicle for the "chance" to knock out a window everything else is modified (rounded) pommel for me. :D

Cool Idea :thumbup: & I'd prolly buy one if produced by ESEE
& I own one of them spring loaded window knocker outters

You mean to tell me your 3MIL didn't break glass? Dude, we've broken a ton of auto glass with a 3MIL. The regular 3 with pointy pommel won't do it, but the 3MIL cruises through it. Like BBQ Boy just accused me of, you must hit like a girl! :D
 
I would not use the point of the blade as a glass breaker unless I hit the pommel with something, In other words using a hammer to hit a "center punch". Problem is you can easily get a glancing blow by trying to strike glass with the point because of where you are gripping the knife in relation to where the point is impacting. Always use the back part (pommel) of your knife if possible since you hand has more control. How do I know this. I tried it on the last rescue I rolled up on. Breaking auto glass is a lot tougher than some think.

wow. you put my diagramming skills to shame.

thanks for all the input, guys. Its really neat to see such interest in an idea thats been cooking in my mind for some time now.

This is why I love this forum.

:D well I have Aircraft Glass to toy with and that stuff is tough.... pressurized aircraft glass is over .50" thick and some sort of plexiglass ??? tough as nails I tells ya :D

I was thinking & typing and I was not clear :D I do that at times ;) I forget peeps dont know what I do for a living :p
 
Ahh..makes sense now, Tony. SOG (The LE Special Operations Group not the knife manufacturer) tested the 3MIL extensively on breaking auto glass. What they found is it would cruise through the first couple of pieces then the point got dull and it was harder getting it to break. So, all you have to do is sharpen the glass breaker tip after using it and you're good to go again. I doubt it will work on up-armored LandCruiser or BlackHawk glass though ;)

Maybe I've heard it before and have forgotten it but are you law enforcement, fire/rescue/ems, or just happen to be in the right place at the right time?

it seems like you could just stick it on and run a piece of paracord through it. then drape the cord over the handle and grip it. if you pull it snug and grip it like you mean it (which you would be doing anyway in this case) it should hold stead enough for you to have a good, solid blow without it pivoting out. maybe i'm wrong, but that seems like it would work and be a really quick application.
 
I am in public safety and can attest to the tip of a knife working. Wouldnt do it with a folder but know an izula can pop a window. Does ding the tip up just a little but hey, if your life is at risk that would be the last of my worries. And for ose who say it could cut you....hold the knife and use the palm of your hand over the rear of the knife. And its a short pop...dont want your hand going through the glass you just broke. These things would be easy to machine though out of aluminum or dare i say Ti so they match the shape of the knive with a recess to prevent spinning and then a machine screw through to hold it together. Tis way the force is not on the screw.
 
I put some thought into this myself and like the idea. If it were me going about it I'd make it so the breaker attached to part of the sheath or something like that. As far as attachment make it a pin with a ball and detent sort of like the pivot pin on an AR-15 so it's always there, and nothing to lose.

Second way I'd go about attachment is to thread both sides of the glass breaker attachment and use some kind of simple wingnut bolt.

I spent some time doing a simplified 3d drawing of how it could look based on the OP:

You could make it a tad more "secure" if the scales had a triangle slot in them then the attachment might be diamond shaped, but the same concept.

Breaking a window was a lot harder than I thought it would be by hand (foot) - was a good thing they were able to roll it down slightly.
 
If there's going to be a special glass breaker attachment, maybe it could be made with a core made of the porcelain used on spark plugs? You can YouTube sparkplugs breaking car windows, and I've seen it in person. According to the "MythBusters" though, the reason they break windows is because the broken pieces of porcelain can interrupted the surface of the glass on a molecular level because of the sharp pieces; I think it could probably be manufactured to do the same. Either way, you can see the difference in how easy it is to break a window with some of that porcelain than say, a big hard blunt object.

I've always wanted to see a glass breaker implement that.

thats almost exactly what I had in mind. ESEE could probably include a pin construction and a screw construction in the package. that way you could choose between fast on/off and a long term attachment.

Too much give I would think. Both in the flexibility and malleability of the material. Using the knife handle (since you couldn't securely grip the sheath) could send the blade through in one direction or another causing injury as well.
 
I figured that's what you had in mind. I'm just getting into knives - definitely loving that there are people from ESEE here to discuss their products with their users. Definitely high on my list of knives to get.

I meant for storage purposes if you didn't want it on the knife all the time. Totally agree with you.
