Kinex DIN874/0 straightedge 700mm

99

DIN 874 class 0 laboratory grade knife edged straight edge.

I use one of these in my workshop and love it, in woodworking and metalworking terms it is unimpeachably accurate, the knife edge gives an unequivocal reading and the angled tip occasionally comes in handy for getting into places with limited clearance.

The edge itself is a substantial 10mm x 40mm bar of hardened and ground steel - the bar dimensions are approximate, all of the focus is on getting the edge within an eye wateringly small maximum deviation on centreline of +/- 4.5 microns (just under a fifth of a thou) of absolutely straight.

The beech handle / stand is divided into three sections and carefully glued to the edge only, this effectively isolates a single contact surface so that the wood is completely free to move in all directions without applying any forces the tool. As well as providing a stable 25mm wide built in stand when using the tool on its back, the wood also insulates the steel from the heat of your hands when taking the edge to a surface, which at this level of accuracy starts to be a measurably relevant factor.

Supplied in a soft leatherette wallet, shipped strapped to a board.
