RoMech Replacement Parts for ROMECH Electric Hot Knife (2“)

Short blade is much more resistant to warping when cutting foam of 2 inches or less.

product works as indicated in description. was able to cut quickly through 3" thick styrofoam easily once blade was heated sufficiently. unit provides various levels of heat although i can't see reason for the lower levels. best reason to get these units is to minimize loose particles flying around when cutting styrofoam to minimize environmental impact which was primary reason for buying this.

The others are too long for the thinner foam and they get too hot and warped badly. These were perfect.

This worked well in the hot knife to carve craft pumpkins. Doesn't get nearly as hot as the longer blades, which is too hot. Wished this one was a little hotter. Still easier than a regular hot knife with x-acto type blade.

what can you say they work, fit in my knife.

prefer this lenth over all

Replacement blade fits perfectly and is sharp.

This doesn’t actually fit into the hot knife. You have to use the side screws and sorta get it to work. Definitely not pro grade
