The Laser 7724 seems to be the only one that comes up.
Please be aware that they are 5/16" hexagon and not 1/4" hexagon, so it is an old style hit-with-a-hammer impact driver they are talking about not a shove-an-18v-battery-into-its-bottom impact driver.
Without wanting to disappear down a rabbit hole, I think it would be difficult if not impossible to buy new JIS standard screwdrivers.Any suppliers can't find much or is it just me?
Need to buy some as I have an engine to strip
