I recently ordered a hot wire short knife. At the same time I contacted your company about having some repairs done on my existing 4" hot knife.
When I received my package with the new short knife, I was surprised to see a refurbished 4" hot knife included in the package.
I just thought I would send you a note to tell you how much I appreciated the replacement item and how quickly it was taken care of. Great customer service is more than rare these days.
Thanks again,
Sean from Hickman, NB

This customer purchased the item at our site.
Around 1987 we started to collect Dept. 56 porcelain houses and accessories and at Christmas made village displays on a 4 by 8 platform in our living room. Around 1990 (we do not know the exact year) we bought the Hot Wire Foam Factory cutting knife to carve out some platforms from Styrofoam for a few of the houses to set on and to create some small hills that we covered with white flannel and artificial snow to make it look like a snow scene. My wife also used it to carve out Styrofoam to insert artificial flowers in to make floral arrangements for our house decorations. She also used it a few times to cut Styrofoam to make platforms for some Easter decorations using Dept. 56 Easter village accessories. Just about every year my wife uses it to cut out Styrofoam to make or remake one or two floral decorations for our house. The 4 inch Hot Wire Foam Factory cutting knife finally broke a couple of years. It could have broken because the knife was not hot enough and was forced through the Styrofoam. This year she wanted to replace it so we went on line and to our surprise the Hot Wire Foam Factory was still being made so we contacted you to see if a new cutting knife could still be used with our old Hot Wire Foam Factory variable power supply. We were told that a new cutting knife would work with it. We still have the VCR tape that came with the original set but we no longer have a VCR that works.

Bought this to build a custom cake stand. I'd been using an electric knife to cut custom cake drums but this is SO much faster and creates a much smoother edge. The knife would always bog down after a few inches into the cut. Very happy! Anna Kellogg
