A while ago I did a pair of orders from Jim Allen with Three Sisters Forge, and I wanted to share these pieces. I'd read a lot about the TSF Beast before getting in touch with Jim, and read nothing but praise for his customer service. After working with him on these two custom Beasts, I have to agree — Jim is nothing but a class act and a real pleasure to do business with.

Here are the two pieces Jim did for me:

Both of these feature a shortened frame from the standard model TSF Beast. I originally placed an order from Jim for a standard Beast. After it arrived, I got inquired about the possibility of doing a Beast with a shortened frame. I have size small hands, so I was interest in shortening the frame to fit my needs. In addition, I was interested in a more low-riding clip position, which frame shortening would also accomplish.

Here's the mockup I sent him to illustrate the shortening:

Here's the first "shorty" Beasts Jim did for me. This is with Jim's new stepped pivot, which gives a fantastic action to the already super-smooth Beast. Jim was able to use the original hole tapped on the lockside for one of the pocket clip screws, so he only needed to tap a new hole on the presentation scale. Super clean.

After the success of this mod, I asked Jim to ask do this with my original Three Sisters Forge Beast. Aside from the shortened frame, this Beast is also a unique in that it has a smooth presentation side. As far as I know this is the only "smooth" Beast Jim as done, and definitely the only one with the shortened frame. In addition, I did a very slight mod to the scales to give the back end extra rounding. I think of this one as my dress or gentleman's Beast, as much of a contradiction as that might be.

Overall, I'm very happy with these way these came out from Jim. The shortened frames fit my hand perfectly and still give plenty of grip and real estate in the handle for my needs. In the pocket, the knives ride super low thanks to Jim's great fold-over clip design. The modified handle frame is exactly 4", just .25" less in length than the standard Beast for an overall length of 7" with the 3" blade.

Big thanks to Jim Allen of Three Sisters Forge for his work on these two. Thanks for letting me share.
 
Dang nice. Far more like the shorty.

Had it a Spydie hole or flipper function, Id have liked it even more.
Ive gone off thumb studs for some reason.
 
I've had four TSF Beasts from Jim Allen: 154cm, two in M390, and the latest one was in S35VN, a gift for a grandson. He does awfully nice work; he returns emails almost immediately, and is an extremely personable fellow...aka "nice guy."
 
that looks really nice , the sharp edges on mine (and the fact that my other custom gets all the pocket time now :p) is why I'm possibly trading ...

92% of Beasts go LE & MIL, they use gloves. If the edges feel sharp either pop it back and I will round for free, or a couple passes with some 400 will do it. Let me know how we can assist. Jim

Now that's service after the sale! Can't beat that. Great job on the shortys.
 
Woah! Fantastic job. That shorty looks neat, and more symmetric to my eyes. Its a wonderful knife, and Dr. Jim is a pleasure to work with, no doubt.
 
Those two came out very nice for you! Great pics.

I've really become a fan of the Beast model and have a few now. Couple older ones.

Just great knives and Jim is just a lot of fun to work with. Recommended for sure. Always seem to be looking for another. Lol.
 
Awesome! Thanks for sharing those great pics! Makes me want to get another one. I love my beast. Jim is a great guy for sure
 
The longer frame was requested so that it could be used as an impact device. Even with the blade closed position it can be grasped and used to strike. We will now offer the "Stuby BEAST" as a model, or will modify existing for anyone that requests. How about $50.00 to cover shipping, a couple belts and a Latte ? Thank you for the kind words. Check us out on Face book, just posted some pictures of the TSF BEAST at work. Jim
 
Blade and flame...you mentioned it has a new stepped pivot...what exactly is the difference? My new one has it too and it is definitely much smoother. I'm curious as to what makes it different
 
With a stepped pivot, it should be possible to fully tighten the pivot screw without impacting the action of the blade. So it should be possible to achieve optimal tightness on the blade for very smooth action - not so loose as to have play and not too tight as to introduce clamping. This is my understanding of the stepped pivot, anyway.

Oh that's awesome. Thank you for clarifying that! I love the action of my beast. So clean and smooth. My old one was very smooth too, but you can tell there's a difference with this new one
 
Yeah, I love it. My Beast with the standard pivot is very smooth and flicks easily (no wrist action), but the new pivot is on another level of ease.

It's very cool that Jim continually improves these models for us.
