Spyderco Assist/ Carbide Window Breaker

Spderco's new Assist boasts a deployable carbide tip advertised as being able to break glass in an emergency.

It's a solid, no-nonsense tool combining a VG-10 Blade with a blunt round tip......a 1 inch razor-sharp flat edge...and about 3 inchs of rugged Spyderedge.

It's designed to be a rescue tool...easily slipped under a seatbelt, and able to chew thru it with no effort.

The heavy Fiberglass-Filled handle (?) boasts deep grasping grooves, and the blade snaps back into place with enough force to cut anything in it's way back in the handle. ( a knuckle of mine unfortunatly) .

Being a "back-lock", it's a little awkward depressing the closing bar of the lockwork...without getting your fingers in the way of the rapiding closing blade...BEWARE!

It's got an ambidextrous wire clip held to the handle with a large screw that feels very solid despite its rather thin diameter.

But the niftiest feature is the carbid tip "window breaker" that can be engaged thru the blunt end of the handle by grasping the blade into the handle..forcing the carbide tip out.

My only concern is the tip only protrudes maybe a quarter inch or so, and I question whether it will really break thru a window in an emergency.

The down side of these kinds of devices, from my earlier testing, is some "emergency glass breakers" really don't work well.

The tips are too soft, and after few practice tries....the tip blunts so it may not really work when needed.

Also, some of the "seatbelt" blades are so dull...they really don't cut at all.

This unit will cut, very well. Don;t know how it'll shatter window glass...maybe it will, maybe it won't. If it's a solid carbide tip..it should last a few tries.

Overall , its a well-built solid worktool for anyone in the rescue biz...though the little built-in whistle on mine doesn't work well...and frankly....is a little silly.

I bought it to keep in my Jeep in the event of an emergency, I suspect it should work well if ever needed.

Couldn't resist trying to see how it would zip thru an envelope: It sucked!
The blunt blade tip worked great to protect the envelope..I couldn't even slide the blade into the envelope because the tip is so thick. I guess that's good news for anyone who's being cut out of a wreck....which is what this knife is all about!

That's OK, a letter opener would suck just as bad at cutting seat belts! Seriously, I'm going to check the Assist out, you've got me interested now...
 
Hi Drshame. Thanx for the comments.

The glass breaker is solid carbide, very carefully ground at the tip to be as effective as possible. I personally broke a lot of glass in wrecking yards while we developed the tool. We changed the tip shape 3 times in R&D on the tool.

We also recognize the long time limitations in carbide, if you look closely at the tail end, you will see that we have made the carbide tip replaceable.

thanx again,

I just received one of these today- bought it to keep in the car, and I might get one for my son, a firefighter/first-responder, if he likes it:)
As you can see, (sorry for the crappy pics) it is quite a hand full- I have big hands (6'5"- 300#). These shots show the tip configuration and I tried to show the window breaker. I found the whistle to be quite loud and high pitched. Typical Spyderco quality and sharpness. I think it is a very well designed knife- form following function. Great work, Sal. A bargain at $60.00.

Sal how hard/easy is it to break a car window with the tip? Can you do it with a little wrist pop, or do you have to use a lot of elbow action. Interesting design specific knife in any case.

I would be quite interested also. We just had a kid die last night when his car went into a lake (rockpit) or a canal while racing a few blocks from my house. Not sure, but I know the street and the lake is on one side and a canal on the other. We lose about 35+ people/year in Broward Co alone from people going into canals. About the same in Miami-Dade county just below us. DrShame is from Miami and can back me up on this. On my 7 or so mile drive to work canals are on 1 or both sides of the road for at least 4-5 miles. Most escape tools are a joke as a local TV station showed with testing at a junkyard. I carry a spring powered center punch taped to the steering column, but it's useless for cutting seatbelts.

Anyone familiar with the "Safety Boy" Rescue Cutter? The Assist may be more versatile all-round as a knife; but specifically for cutting belts and breaking glass, the Safety Boy appears to be both safer and more effective. A little more expensive, however.

I'm interested in getting one of these as well.

The thing that concerns me is how to mount it in my car, so that it is accessible in an emergancy, yet safe in a crash.

Any recommendations?
 
I tested a series of so-call"life hammer" type devices.....most were available thru cataloges or mall outlets.

Most were crap, with points made of such soft metals, they bluntly badly and required mutilpe hits to break anything.

Making matters even worse, the blades in some were thin base-metal that wouldn't even cut thru a seatbelt.

Sal's Assist is exceptional, and I believe it when he says he's broken lotsa glass with it.

The "winner" in my test with the City of Miami Fire Dept. was a little keychaion accesory called the resque-me. A smal zytel spring loaded, carbide tipped center punch, with an integral razor blade safely tucked at a 45 degree angle in the handle.

But again, I found the "Assist" to be a solid performer that looks like it could last quite a while, and peform well in the worst of circimstances when it's needed the most.
