View Full Version : Looking for a certain shape...

10-06-05, 03:52 PM
I have a project in mind...

I'm working on protoypes using Kankaanpää "saami" blades that I got from Dennis H quite a while back, but the blades don't have quite the right shape.

To make this work right, I need a blade with bevels that go up 2/3 of the blade's width, or that have a lozenge-shaped cross section, like in the attached sketch.

These Puronvarsi blades look like they might do the trick, but has anybody seen one, to be able to tell me what the section is like?


Or can anybody suggest an alternative?

I have one and the profile is rhombic as the Left hand sketch of your thumbnail.
Brisa list another blade as rhombic X section as well.... the Lammi blades in three styles.

The Puronvarsi blade I have is 80x19.

The cross section on the right is the correct section.
top =3mm ,come down 8mm , 4mm .
hope this helps

i think mic is suggesting it's inbetween the 2 pictures.

That the spine is 3mm thick. At the thickest part, which is 8mm below, the blade is 4mm thick, tapering to the edge at 11mm below that.

This is not near enough the 1/3 - 2/3 ratio that I need.

It looks like you need "Tommipuukko" diamond section but just bigger blade...?
Have you looked for Hankala blades? They are quite expencive for prototypes but they are good quality.
