theres ones available that are made using a special no spark alloy, like the kind you would use in a refinery, they dont spark if you hammer them into brick or drop them,very expensive and only really used in mines and petrochemical etc, quite difficult to buy as well as they are special order....dont think it will be them unless the company bought in a load and issued them out for a previous job...which I doubt...
Apart from that I know that SNA PON tools (USA and UK) sell screwdrivers with yellow handles, have they bought over a famous orange handled company with the fish n hook picture ? sure I heard that somewhere... theres salesmen go round sites and sell these and if they are appealing, a lot of tradesmen pull out their wallet and add to their collection of tools...
