Dremels make one hell of a mess, plus I worry that the dust may be harmful. In the end they really don't remove as much material as you would expect either. The best thing that I have found is to go to the dollar store and buy some cheap steak knifes.

 

Fingers, a steak knife, and a night without any other plans.

 

LOL. Thank you both. I will clear my calendar.

 

Got to agree a steak knife works really well, I think the key is something serrated

 

I used a pen knife. Worked well.

 

I use a bread knife for larger trimming and as others said a steak knife for smaller stuff.

I've found that the this razor blade scraper, or This , or an x-acto knife are wonderful tools for foam carving.
I'm about to post a build log of a huge buttress root that I've made with foam.
Another super useful tool that every frogger needs to make is a hot knife. Easily done with guitar wire and a power supply.
Hope this helps.

So I don't have to resort to You Tube, where I ALWAYS get sidetracked for hours...can you explain the "hot knife" DIY??? It is a good tool for stryo, and I've done some interesting carving for a viv with it, but they really can be fragile.

 

Youtube is a great resource for hotknife and hotwire DIY projects. I built mine in a matter of 30 minutes with some guitar string, 1" PVC, speaker wire, and a power supply. If you want something a little more robust, and professionally built This would be a pretty cool option.
