Hook Knive

Recommended Posts

The line-over is most likely a steering line. If you wanted to cut a steering line in order to clear a line-over, pull the toggle on the side with the line over down, away from the other lines, and cut the line. If your canopy will not fly strainght after clearing the mal., either compensate for the turn with the rear rsier on the toggle-less side, or cut the other steering line, and flare with the rear risers.

Incidentally, if you have a line-over (main or reserve) releasing your brakes and pumping the toggle on the offending side can clear the problem. Of course, remember your hard deck if this is on your main. If this is the reserve, try once or twice, then cut the line. If you don't have a hook knife, keep trying to clear it, or see if you can find a way to make the canopy fly straight (or straighter) before impact.

Lets say you're under your reserve at a "high" altitude after a FF jump (or RW jump), so you're under your reserve at 2k. You have a spinning line over, so you're spinning at the ground doing 70mph. Thus you're going to come in contact with the earth in roughly 18 seconds.

Step 1: Get hook knife, don't drop it.
Step 2: Find the offending line, while spinning violently at the ground.
Step 3: Cut the right line, drop knife, fly canopy to the ground safely.

Quite honestly, the chances of you being able to do that are so slim its not even funny. Would I do my damnedest to try to do those 3 steps? Yup. Would it be successful? I don't know, probably not, but I'll burn in trying.

I think that most people's reasoning for having a hook knife is scewed, since cuting a line on a line over reserve would be pretty difficult.

Quite frankly, I carry one (jack the ripper) for normal jumps and its more for the chance of being in an accidental non-intentional CReW wrap. That seems more likely to me and being that most jumpers don't do CReW and don't know basic CReW emergancy proceedures, they'd probably cutaway christmas wrapping whoever they wrapped. Thus, the hook knife.


My favorite hook knife: Jack the Ripper. Its big, it has easly replaceable blades incase they get damaged, its easy to grip and sews nicely onto jumpsuits.

Thanks!
As you can see (on picture) I have mine on my leg strap.

"Inside the mudflap works well because in most emergency situations, that part of your rig will be accessible. Also, it is secured in place - no fumbling around if you need it"...

That`s why I`m asking....because I know, that if by any reason I`m spinning or I`m entangled it will be easier to close my arms to my chest than try to reach for my legs (or hips in this case).

A line over on your reserve and you would be "ill prepared".



I think it would be best not to try to cut a line over in a spinning reserve, scares me more the idea of cutting a wrong reserve line than going down to the floor with a spinning reserve. Maybe somebody with more experience can tell me more about this.



Since the offending line is almost always a steering line, simply cutting the steering line on trashed side will likely address the problem.

If you had to figure out which suspension line it was, you probably couldn't do so before the ground intervened.

Why would you do nothing? Would you do nothing if you had a total on your main because you were afraid of pulling the reserve handles in the wrong order. Of course not.


I have the reserve, so am going for the reserve but having a line over on a reserve and cutting the wrong line? nice. There is a very old thread here of somebody doing tests with line overs using the hook knife to cut the line and he said that in the test a couple of times he cut the wrong line, good thing he still had a reserve (he was using a cutaway rig or was trying it in a hanging harnes, cant remember).

Anyways whatever I say here about that situation might be BS because nobody has an idea on how he/she will act in given situation.



You can still cut the wrong lines and have a steerable canopy. we should have the intervention of Bill here or informed Moderator to clear this up and give a proper account of cutting the wrong line, finding the right one, just a general procedure would be good. Any CRW people would know this already.

I talked with a local "CReW Dog" who said that they have sat around and tested all the different hook knives on actual lines with tension. He said that the "cheap plastic ones" always broke before cutting the lines. I would say if you're going to jump with a hook knife, make it metal or Jack the Ripper...

;)Always is a lot!
Let me know who the crew dog is and what manufacturer of knife they were testing. I don't use the "cheapies" on my gear but have several in my shop/loft that work just fine cutting lines. I don't use them on my gear simply because they are too little for my hands and I want something "big" to grab when needed.

I'd like to recommend the "Raptor" as another good hook knife. It's much like a "Jack the Ripper", but is completely aluminum. Very well constructed and very solid. Sells for about 45$ USD.

It might be a bit too "hardcore" for most people though. But I use it as my main HK on my CReW jumps. I also keep a smaller aluminum knife on the front of my right leg strap.
