My very simple thoughts on this matter: The rivet is a conductor. We have no way knowing if the coating between the rivet & the blade is compromised or gets compromised during use. Because of that, if due to field expediency, you needed to use a scrap yard on a live wire find another way to insulate yourself & don't trust the knife. Be it making a bit of a poleaxe & lashing the handling to an insulator or something else. Anything else and it will be a crap shoot which could lead to serious injuries. <img src="/ubbthreads/images/graemlins/frown.gif" alt="" /> Yes, looking at the pics on the SY website, the rivet does have definite contact with the handle (how else is it suppose to stay in place without some sort of adhesive?). If you keep your hands away, as Kraz said, from the steel rivet it should fine. That is, if Res-C has good electroshock insulating properties. That's what I kinda want to know. You are right about using something else as an insulator, but you don't get as much control. There is still a need to push down on the knife.... I guess you could make a naginata and just slam the edge into the live wire and it would just severe it. Though what if you have nothing? <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" /> Honestly, though, if anyone here on the forum is gonna do live wire cutting, I'm pretty sure they'd be carrying a electroshock tested wire cutter.

I bet Res-C is fine, it is just that lanyard bushing that others already mentioned. I only know of one knife that advertised compleat insulition from the blade and that was the Gerber LMF they had a picture of one that a US sniper had used to cut big eletrical cords that were going to a search light aimed on finding him and his spotter, the blade had a big melted chunk out of the center but he was alive to tell the story. Yep, I've got one of them LMFs. Decent for the money. The glass punch is kinda cool. If you look on the pictures at knifetest for the LMF you can see the tang construction. It's quite impressive and makes sense that it would completely electroshock insulated. Res-C, maybe, still trying to figure that out the safest way possible.

I think this shows that a little knowledge is dangerous. I saw an extremely intelligent induvidual(we were about 12 at the time) stick a paperclip in an outlet at school, using a wooden pencil for insulation. It arc'd from the paperclip through the eraser(insulator) to the graphite through the wood(insulator) to his hand, sent sparks everywhere and he was just standing there blank like his soul had been ripped from his body. It turned his lips and fingernails purple.
Real life is a lot more complicated than it is in the books. Not touching the rivet is DEFINITELY NOT adequate protection. I wouldn't go anywhere near high voltage or high current. The voltage threshold through soft tissue is only about 4 volts. Don't mess with it. Respect the power. Don't forget that air can conduct across a high enough voltage. The closer you get, the less voltage is required.
We had an automated fullerene-manufacturing reactor in a lab I used to work in that ran around 30 volts, 100 amps across a carbon arc in nitrogen atmosphere with a gap maybe half an inch and that was enough to generate 5000 degree gas temperatures. Electricity is definitely not something to be taken lightly.

I would have no doubt about ResC being a great insulator, however the protection is only as good as the weakest link. <img src="/ubbthreads/images/graemlins/shocked.gif" alt="" /> I second that notice ,TTD

Electricity is definitely not something to be taken lightly. Yea... pencils lead, in certain school experiments, usually testing for electrochemical cells reactions, is sometimes used as a medium. Quite a good one too. Definitely don't mess with an outlet. I'm just wondering about the electroshock insulation if I, or someone, accidentally cut a live wire (that seemed dead) and if I, or he/she, would live. 'Course, I don't just go round randomly cutting wires.

The only way to settle this is a high voltage chop off. You first. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
