Review on ALLY Tools Precision Sharpener Scribing by Andy Mitts

I bought this to replace a pair of compasses I bought at an art supply store which had a plastic screw for attaching a pencil. It was more expensive than this and was very inaccurate due to the plastic screws. There is no plastic in this compass and I am very happy with the quality. Strong, easy to tighten screws. Opens to approximately 22 cm or 8.66 inches. Very strong metal screws ensure high precision. I highly recommend this product. See photo.
