I use the Precision Engraver to carve bricks and stonework in my holiday village displays, where it turns an otherwise tedious task into a breeze!
This tool may not be the best approach for those going for realism in a very small scale where the tip might be too big for very fine lines (I'm thinking true realistic scale models).
However, for the stonework in holiday village displays, where true scale doesn't matter as much and we're not always striving for perfect realism, the Precision Engraver is a true lifesaver!

I use a number of HWFF tools to create holiday village displays, but this Sculpting Tool is by far my most used. I use it primarily for carving cliffs and rock edges, and its quality craftsmanship allows me to slice up pieces in no time.
The blade can be bent to carve shapes, but I find it too flexible for this purpose (for this work, I use the Freehand Router Tool). 90% of the time I use the Wire Tensioner addon, which I HIGHLY recommend.
The Sculpting Tool is an absolute workhorse, and I recommend it to any foam hobbyist.

We love it! It has allowed our imaginations to range free at last!

This is great stuff. Not a glue, it actually fuses the surfaces, and you can cut it easily with the foam tools. Regular glue hardly worked, but this is super!

We have been using this product for a number of years and find the product durable.
