- Durable Construction: Made from 3D printed PLA and 304 stainless steel. These parts have been designed to maximize the strength needed for polishing out stray grinding scratches.
- Stone Size: Holds 1/2″ wide stones up to 3/8″ thick, with 1/4″ thick stones working best from my testing.
- Large Stone Holder: Sized for stones that are 1.5″ to 3″ in length. Longer stones have been used in this holder with success. These longer stones have been ones 1/4″ thick.
- Short Stone Holder: Sized for stones that are 0.75″ to 1.5″. Longer 1/4″ thick stones have also been used in this holder too.
- Universal Fit: Designed for smaller compact reciprocating saws but compatible with most standard models. Some saws with longer strokes may require guard removal that usually unscrews or is easily removed.

Prepping Stones for Use:
Standard mold polishing stones come in 6″ lengths. The SL stone holder has be designed so that the stone can be cut in half for easier use when using tools. For cutting, I have fund the easiest is to use a small chisel and score a line win the middle of the stone and then place the chisel on the line and give a quick tap with a hammer.
