John Cryderman (from Chatham, Canada) is well known for making high quality strip laminated and Birch plywood boomerangs. Many of these models are John's original designs. However, he occasionally makes replicas of boomerangs made by other famous boom makers, such as strip laminated hooks and omegas by Al Gerhards of Downington, Pennsylvania. John usually makes his strip laminated boomerangs out of native Canadian hardwoods, but he sometimes use exotic woods, such as Mahogany and Ebony. Some of the plywood and strip laminated boomerangs are decorated with inlaid plugs of exotic woods arranged in pseudo-floral patterns. The vast majority of John's boomerangs are large in size and they require a strong thrower in order for the boomerangs to make a full return.

This copy of an unweighted Gerhards hook was made out of strips of White Oak and stained dark. This is an unweighted hook that is light weight and perfectly tuned. I test threw this boomerang before listing it and it is very easy to throw. It has a beautiful circular flight with a range of about 40 metres. It reminds me of how Al used to tune his own unweighted hooks. This boomerang is signed and dated Nov 1992. There are also some penciled notes written on it with instructions for throwing. Excellent condition!
