If you haven’t heard these Tusk Silent Timber blades in operation you can’t fully appreciate what a difference they make. They are not silent but they are significantly quieter, and probably never squeal. These ultra-thin, deep-cutting, premium-quality saw blades are made especially for use on electric or cordless circular saws. They feature a patented sound and vibration cushioning design with a silver fluoride coating and tungsten carbide welded tips. They are especially useful in noise restricted environments, but they are better at any time. The dense solid steel core design results in smooth, precise cuts, and the ultra-thin kerf reduces load for longer blade and battery life.
Pricing for 165/185 x 1.6 x 52T x 20/16 blades starts from $70. See tusktools.co.nz to find Tusk stockists.

A butterfly takes wing
This simple butterfly pendant or brooch (depending on the back fittings) is a very good exercise in several basic goldsmithing techniques. It also can be decorated in several different ways to produce strikingly different finished pieces of jewellery.
I drew this design more than 25 years ago for a company that then made paua-shell jewellery. They stamped out their products, so I often made the master patterns in copper and from these patterns they spark-eroded the dies.
If this design was being made in an art school, it would be stuck to a sheet of silver and the basic shapes cut from there. If a design was made this way in, say, 18-carat gold and the wing outlines (as here) made from 2.5 mm thick metal, the outlay and waste material would be considerable from a 2.5 mm-thick sheet of 18-carat gold plate. But we will make it like a professional craftsman who has to live in the real world where costs matter.
