Hi all,

Recently I received 2 knives. Both are made by a maker last name Zinzmeister. I have not heard of this maker before but I must say his work on these slip joints is awesome. The feel so nice, joints are pretty tight and the snap that slip joint has just keeps me thinking about it. The guy who sent me them says he got them directly from maker in 2001 I think.
Well my mission is to replace the ivory micarta one with some mammoth ivory, a daunting task for me made more difficult by the fact that the FF is hardly lacking.

Any way, now that I have seen and handled these knives, I just have to have a go at making one. Could any of you slip joint makers share a couple different traditional patterns with me? It would be very much appreciated.

and here are some pics of the Zinzmeister knives.

Start drawing. Draw more. When you think you have it, go to sleep and look at it again the next morning. Make a simple model out of soft wood to get a feel for it. Play with it an entire day.

Many times what looks great on paper won't look good irl much less work properly ergonomics wose.
 
Drawing is the key, we don't magically make slipjoints because we have a pattern.
A gun show beater can be priceless for the learning curve. Get one, take it apart and go
from there--- you're still going to be doing a lot of drawing. Once the mechanics start
to make a bit of sense draw some more,..... then the fun begins!

Buy "Slipjoints My Way" off Amazon by Don Robinson.

It will shorten your learning curve dramatically. Also, like Ken said, draw and find an old knife to take apart. It's seriously very hard. Addicting and hard.
 
Thanks guys, While I do like to draw and make regular old sketches, I am looking for traditional classic patterns. My method begins with a decent image with minimal perspective issues, I then import it to CAD and make a working 3-D model, from there the components each get their own dimensional drawing with "production" notes. I know, a little overkill but hey at least I know If it does not work right it is my own F&F that is the problem not the design :)
I did get some templates from Mr Shaw! Thanks! Love that swayback jack
