How do you knife builders make a v slot out of brass for a bolster on a knife.
I am trying to make one but not having much progress.
Cheers guys.

Exactly! Drill holes, and file... Don't rush. You need set of needle files.
Perhabs this will help..

The rather flippant comments above are correct but you may need a V shaped needle file to do it.
If its a Lauri blade can I recomend a lauri bolster but they do restrict handle style. The bolster can be wood too you know and a little persausive force can help but also with metal. making one from scratch can easily take several hours.
Here is a factory bolster fitted with care

But you need to thin the tang up to the last few mm from teh bolster position like this

Thank you guys.
@Puchal, that was informative, thanks.
@brancho, many thanks for the detailed response.
If I could have gotten myself a bolster for the M Eklund of Sweden blade that I have I would, that way all would have been much easier. This is like the blade, mine is sand blasted. http://www.art-knives.com/shop/images/b_9.jpg
I have some 3mm brass plate a few needle files like the ones you have recommendatory, I broke two, I'll get another set.
Wooden bolsters, I have some oak that was cut down in 1956 and used for a fence post under the eves of my house, been in the garage for 17 years, interesting.
I am also playing around with a dozen other blades all same type, handles are made for four of them, just making sure the wood is dry.
Funny you should mention Lauri blades, I was going to get a few of them.
Cheers mate.

Now I see you have a blade that changes thickness from top to bottom.
The answer I was told when I asked on BB HERE was be patient and take your time basically.
A tip I found was to put pieces of masking tape along the lines you are aiming for to help achieve straight lines. Also keep an eye on teh back of the bolster and keep teh slot wider at the back so it is possible to tap it the last mm or so.
