Will it Work for 2" thick XPS insulation board? Stuff is a pita to cut with a regular sharp blade. hard to make clean cuts.
If you want quick straight cuts, your old chef's knife works awesome for that. Keep a cheap electric sharpener in the garage to freshen the edge often. I also have a whetstone with diamond surfaces for a finishing touch.

My older 10 inch chef's knife works great on all sorts of insulation board, including 2 inch XPS, and fiberglass batts too.

If I need curved cuts, I'm either getting out a snap blade razor knife, setting up the nichrome hot wire bow, or making a huge mess with a rasp.

Tried that with a few different knifes, it never scores cleanly for more than a few feet, not sure if i am doing something wrong or what but instead of scoring it cleanly, it skips across it and makes a buncha divot holes.

Have read online to try the smallest cheapest disposable razor knife, so I am going to try that next. Have previously used much more heavy duty blades.
These materials are tough on blades so you may have to dispose of them or rehone them frequently. As far as technique, keep your blade extended long and pulled from a low angle so that it gives a very shallow cut. This gives the most mechanical advantage to the blade as it wedges through, cutting less material with more blade with each pass, which means less pressure at any specific point on the cutting edge. This helps the blade keep its edge longer and deters material from bunching up in front of the blade and binding.

'Unfocused' has the right idea with an old 10" chef's knife. I also have one that I use for insulation and sharpen coarsely every few passes.

'BeautifulVest1304' may be on to something with the putty knife. In a pinch, I've been able to score foam with friction alone, by running it along the edge of a table or outside corner on a wall. Not practical for large pieces, but it brings us back to the concept of heat.

I'm thinking of getting this for cutting slabs of beeswax into smaller pieces. Any thoughts on this from those familiar with this tool?
Unwaxed, unflavored dental floss is a good choice to cut honey comb and beeswax in general. By hand or in a coping saw. Or use a coping saw with the teeth ground down. Or string your coping saw or hacksaw saw with a steel guitar string. These all work nicely.

A narrow bladed pocket knife, like a French Laguiole, works well. Maybe a cheese knife?

If you're uncapping, just buy a serrated uncapping knife, either heated or unheated.

My brother is a beekeeper. He doesn't use heated knives for anything. He says he just doesn't need them.

I got the harbor freight one and it is good for cutting foams for gun cases
You read my mind...was going to built one of those 'hot wire cutter' setups, then this post triggered an alert and it made me pause. Smilie

These cut through foam like 'butta' with that 5"+ blade?
