Kunz Flat Spokeshave Review By: I.Ball

Category: Spokeshaves

Manufacturer: Kunz

Tool Type: Spokeshave

Model No: 51A


This review is about the German made, Kunz 51A spokeshave.

The Kunz 51A has a flat sole / straight bottom.

The 'A' indicates the spokeshave is 'Adjustable'.

The Kunz 51A spokeshave is made from grey cast iron with the Kunz bright green finish and a bright red lever cap.

These adjustable spokeshaves are 250mm (10 inch) long and are equipped with a 51mm (2 inch) wide cutter and with a fine blade adjustment mechanism.

The blade can be accurately adjusted by turning the two knurled nuts situated just above the top of the blade.

Each nut moves the blade on that respective side upwards or downwards as the nut is turned.

The blade is secured in place with the red lever cap. The lever cap is secured / loosened using the lever cap securing screw.

The handles are arched and raised slightly above the core middle section.

Each handle has a circular hole cut in the end to allow the tool to be hung from a hook in the workshop.

The Kunz 51A with its flat sole / straight bottom is suitable for a number of fine shaving applications including on convex curved edges.

The tool can be used by pushing or pulling the shave to produce fine shavings.

The spokeshave is usually used with the cutter set in the bevel-down position with a good sharp edge. The cutter edge shouldn't be set too far out that it creates too thick-a-cut or wedges and not too far in that it barely takes a shaving.

As with nearly all tools it is important to regularly sharpen the blade to ensure a sharp edge is always in use; in doing so it will create far better results and a lot less frustration.

This spokeshave design is heavily based upon the Stanley and Record flat spokeshaves with the obvious difference being the colour.

The Kunz 51A flat spokeshave is also made with a round sole in the form of the Kunz 51AR round spokeshave.

"Just stumbled across your website and an absolute treasure trove of information. I was recently given an old Stanley 110 block plane and wanted to know more about it. Your website told me everything I needed to know.

But there is so much more to read. I forsee me spending a lot of time just reading page after page. I can appreciate how much time this will have taken to put together.

I just wanted to let you know that your hard work is appreciated."
