Tools for the Workshop

Abstract

Evidence of careful thought in the design of adjustable spanners and wrenches is welcome. The adjustable spanner that slips round the nut and causes barked knuckles docs so for a number of reasons; Humphris & Sons Ltd. have investigated these reasons and have produced a new range of adjustables which they claim have none of these faults.
