Jointing Chisel - Rennsteig, 250 x 60 x 13 mm, Polished, Safety Impact Head, 385 060

Rennsteig 385 060 Jointing Chisel, 250 x 60 x 13 mm

Rennsteig 385 060 is a jointing chisel 250 mm long with a 60 mm blade. It is made of high-alloy tool steel, hardened throughout its section, and weighs 545 grams. Made in Germany.

Hardened throughout

This is what separates it from cheap chisels, where only the edge is hardened. On a Rennsteig the whole body is hardened so it carries the blow without loss - the hammer's energy goes into the material rather than into deforming the tool. The second consequence is that the edge can be reground many times without reaching a soft core.

The safety impact head

The striking end has a special safety impact head that will not splinter or mushroom under a hammer. A split head on an old chisel is the classic source of steel fragments flying towards the eyes - that is precisely the failure this construction removes.

The flat-oval profile

The body has a flat-oval section of 26 x 13 mm rather than a round one. A flat profile will not roll in the hand under a blow, and it lets the edge be held at a precise angle to the joint - working mortar, that angle decides whether the joint is cleared or the brick is broken out.

What it is for

The primary use is construction: raking out joints in brickwork, removing old mortar, forming chases. The 60 mm width is the compromise between speed and control - a wider blade covers ground faster but asks for a heavier blow.

Standards and approval

The tool meets or exceeds the requirements of current standards, DIN among them, and is GS-approved. The GS mark is an independent German safety assessment - on a struck tool that means the material and the head have both been tested.

Polished or painted

Rennsteig offers article 385 060 in two finishes: polished (385 060 0) and painted (385 060 1). The tool is the same and both carry the golden dip coating; only the surface treatment differs. The photograph shows the polished version. The same chisel is also made in 50, 70 and 80 mm widths.
