Spiral Contrabassoon Reamer by Crook and StapleThis spiral contrabassoon reamer ensures that the tube of the bassoon reed remains round whilst you are reaming the reed out. It features an optional depth stop so that when you ream your reeds they are all reamed to the same depth. This allows for greater consistency between your reeds, which is of paramount importance. You can choose the depth stop next to the Add to Cart button. The wood used for the handle varies.
