Thread: Emergency Services Rescue Knife

I play in the shed in my retirement making things to keep me occupied and for the last couple of years knives seem to have been the main item of interest
Full youtube video on the Emergency Services Rescue knife I have just completed.

That is a lovely blade, with a very thoughtful sheath. It's an awesome combo, and one I would not object to being in my collection, but as a rescue knife, the blade is too pointy for my personal preference. Please take this as constructive feedback - I don't mean to detract from you at all. You have some serious skills.

My EDC includes a Benchmade rescue hook. The reason is my son, now 20, nearly left this mortal coil by putting a cable tie / zip tie around his neck, and pulling on it, when he was just over 2 years old. I had spent some time as an ambulance volunteer in South Africa, so I'm not exactly green to rescues that are somewhat hairy. However, nothing handy, other than a pair of blunt sidecutters in a drawer could get under the skin of his neck, and then only with a dose of olive oil that was handy in the kitchen. It left a ring of little blood blisters, but he was okay. And didn't need CPR. Two minutes more, and he would have been history.

Now, my "test" is if you can cut a cable tie that has been pulled tight enough to indent about 1cm into a pool noodle without damaging the pool noodle, you're onto a winner for a rescue blade or tool. Having said that, a Leatherman also rides in my bag, for when I fortunate enough to have a piece of biltong.

@Mauser308 - the design you posted has promise. It bridges the gap between person rescue and more general use, and definitely has more practical utility than my Benchmade, which is so limited in what it can cut that you can take it though airport security in carry on! It is an extremely good option for clothing, seat belts, fishing line, paracord and even boots. The ability to pull without fear of collateral damage is reassuring, and it doesn't require much in the way of training or practice to be proficient. The blunt tip design doesn't need a ring, because the force of a push is directed forward, and the guard is sufficient to keep the hand in position. Think about keeping the angle of travel correct by the design of the top of the handle and the angle of the tip, so you don't end up with forward force dripping the blade down when pushing it. Am I making sense?

The ‘viper’ cylinders that BOC offer are useless for purge welding.

They are a combined regulator/flow meter.
If you want to purge, you need to fit an additional pair of flowmeters to split it. If you want 10L/min at the torch, and 8L/min for the purge, you have to set the cylinder flow meter to 18L/min. So when you stop welding to reposition, the purge is getting the full 18L/min. Causes a lot a pressure variation and turbulence.
