I would always heat as much of the scalpel as possible until The handle became too hot...maybe he does the same
Yeah that happens quite a bit haha. But usually I try not to flame more than just half the blade. But even then if held too long the heat transfers to the handle which I don't like lol

Yeah. I use an Xacto and another type. Which the second type helps tremendously in heat reduction and excess alcohol drips. But with the tube expanding and contracting due to repeated heat cycles has made it loose. Which in turn makes me a bit paranoid the blade will fall out. Although it hasn't yet lol. This screw type is very secure and whatnot. It's just the rattle of the comfort grip tube. But when your not looking directly at it and feel the blade rattle. It annoys me haha

A.k.a said: The #7 handle is great ime. I also have never had it get hot all the way down, with my old flat handle it would get a little warm if I really went at it but thatβs it.
I get the entire blade red and then sometimes do all the way to the part where it slides onto the handle.
Are you guys torching the whole handle also?
Yeah I have a #7 coming tomorrow as a matter of fact haha. I usually only torch about 1\2 of the blade.

About the self heating blade, seems like if you knew how the shit worked you could easily rig one up with parts from a vape shop.
The first time I used one that auto heats when you take a drag blew my mind. The speed it can heat up at is insane.

Main problem is, vape shit can heat coils to glowing easily, those have fairly straightforward resistances, and that's what the power sources are aimed toward. A blade however, is a lot of metal compratively. I don't think even two 18650 batteries are gonna heat a whole blade up effectively. You have to first get the blade to complete a circuit, then finding the amount of power to heat it, that definitely is gonna take a wall plug imo.
I would scratch that idea for now.
I would say in the OPs design that a smaller heat sink more toward the base, OR an insulated covering over the current design would alleviate the issues associated with having most of your handle be a heat sink. There is also the slight issue of all those crevasses never getting hot enough to sterilize, but being so close to your work.

I hear you. I used to build vape boxes and what not and played around with parallel and series builds. And I'm pretty sure if you could complete the circuit and have everything else well insolated a single 18650 could heat the blade to a glowing red. And definitely could in a series builds with dual 18650s. But the issues with that would be a huge heavy clunky self heating blade π. But on the subject of the prototype sketch. I just drew that up in like 5 min. I'm pretty sure you could get by with 1\4 of the length of the heat sink. The design wasn't totally thought through π. But that's another reason why I posted here. Just to get feedback and whatnot and to discuss everything. Which I definitely appreciate all the kinds words and criticism. It's super helpful!
