I just wanted to give a big thumbs up for the newer renditions of older handle designs :thumbup::thumbup::thumbup:

There have been three handles that I consider to be upgrades of previous handle designs, that appear to have fixed all of the problems I found with the previous handles. Specifically:

3rd gen becomes BOSS street/jack
fusion becomes BWM
ergo becomes TTKZ

In my experience the 3rd gen handles suffered from 3 things. The index finger position wasn't tall enough compared to the middle finger to pinky positions. This meant that the front of the knife felt like it was kind of dangling in your hand, to me the knife felt like it constantly wanted to fall back in my hand, like I my hand was slipping towards the blade. The second problem was that the slope from the index finger to the center of the gaurd was to obtuse, it extended the length between your index finger and edge needlessly and didn't give you a 'locked in' feeling when holding it in a tight grip. If you stabbed something hard, the combination of a not-tall-enough index finger position and the wide curve up to the gaurd allowed the hand to shift forward more then was comfortable. The third thing was that it was a uniform thickness all the way across, this isn't really a problem except that it didn't help the lack of security caused by the first to problems, a little palm swell would have given the handle something more to grip.

The BOSS street/jack handle fixes all of that. It's index finger position is made a little taller, it's middle to pinky position is made slightly less tall, the curve up to the guard is made more accute giving you a secure locked in feeling, and the handle has just enough thickness variation to give you more grip.

This is resinguys image, it's the best example I could find of the two handles side by side. I can remove the link if necessary.

The Fusion handle suffered from three issues again. The Pinky position was very small compared to the index finger position. That made it feel like the knife wanted slop around on the back end while chopping, it also made it feel like the knife wanted to slip forward in the hand, putting the weight and vibration on your pinky as you chopped. Because there wasn't enough pinky material to get a solid grip on, you wanted to grip harder with the front of your hand which would wear your grip endurance out prematurely. The second problem was the height and curvature o the palm and finger swells. They created an almost circular swell - too severe for my palm or fingers, I felt like I had a hard piece of metal pushing against my metacarpals when I gripped down hard on it. I've got decent muscle padding on my hand, but not enough to reduce the shock going to my hand bones with such a severe swell. The third problem was an exacerbation of the palm/finger swell by having the center of the scales flare out in a round fashion. It made the knife feel like you were holding a hard ball in your hand from every angle. The combined effect was a knife that felt sloppy in the hand, it wanted to rotate as you swung like you were doing a wrist snap (even when you wanted a solid hand/arm swing without a snap) and it felt like it was mashing against your hand and finger bones more then it needed to.

I have no handled or owned a BWM yet, but from the images I've seen it appears to fix every one of those issues. The pinky finger position is made to be taller so that it is more in line with the index finger position and the palm and finger swells have been lengthen in their curvature so there is not as much of a "round ball" appearance. The curvature leading up to the gaurd has also been reduced giving it the possibility of a much more locked in feel.

The Ergo handles had three issues as well. The index position was again too short compared to middle to pinky positions - you were left wanting more grip in the finger that best controls the knife. The pinky position was HUGE, much taller then it needed to be for most people except those with huge hands. The scales were boxy which put corners in your palm and fingers as you chopped, and the scales were flat, they had no variation in thickness. Because the handles were so tall and flat, it gave you a feeling of good control against torqueing and it gave you a good index for the position of the blade when you had to grab it blind making the badger attack one of the better combat knives busse has ever made (stout, indexable while working blind, excellent control over torque), but for chopping it hurt and didn't feel quite right.

The TTKZ fixes all of that. In spades. It is the most secure feeling chopper handle of any busse I've handled, of any knife in general. It is made to be solidly in your hand. The index finger position to pinky position height ratio is close to 1:1 and the palm swell is nice and wide so it just sinks into the natural curvature of the hand without jabbing into the bones. T scales are curved in a way that makes them feel round but tall/flat enough that you maintain control over torsional forces. It is an amazing handle.

All in all these are pretty stellar upgrades that fix every major problem I experienced with the older handles, creating, for my hands, handles that are without major issue. They feel solid and comfortable in the hand, perfectly suited for the given size and tasks. Now if I could just get a nmfbm with a BWM or TTKZ handle that would be awesome.
 
Nice thread LVC! :thumbup:

The BWM-LE (never had a CG, but I doubt there is much difference) handles fantastic!

I agree, very cool thread. :thumbup: I would love to see a test team handled steel heart.

After using every knife in that pic the only complaint I had with Popeye (the NMFBM) was that during heavy use the middle hump of the mag handles was a little too thick for my hands. That called for me to sand it down thinner which resulted in the black layer being on top in the middle and then it was very comfy. But since both the TTKZ and the NMFBM were over two pounds and within a couple ounces of each other I still preferred the TTKZ enough to keep it and sell the NMFBM. In fact, that is the only knife I don't still have from that pic so I replaced it with a much lighter 29 oz .27 saber FBM with handshaped mags in the pics below.

To me, the TTKZ handle is by far the best non res-c handle of any I have tried from ergo to present, but the fusion mag handles when matched to your individual hand are a very close second and BWM comes in third due to the funky forward swell in the belly of the grip. I haven't tried the old straight handles but don't really want to spend the money to do so either. The B11 on the bottom is one of Jerry's asymmetric grind ones and my most comfortable and heavily used of all my over 10" blades. That snakeskin CGFBM was the biter of the bunch due to being thin and sharp in the pinky area you mention. That was easily fixed with a couple minutes of sanding.

Hand size is always a factor and more than most people realize. I am lucky enough to have paws similar in size to Jerry and Dave Brown so most of Jerry's designs fit me pretty well. Yes, that is a hand shaped mag fusion handle under that meat hook.

This particular blade feels like it was made for my hand as is, which is always a nicer feeling than knowing you will have to sand one down.

I wear a size large glove. using these measurement guidelines:
http://www.glove.org/glovemeasure.php

I have a 9" palm circumference and 8" from the base of the palm to the tip of my middle finger. It "fit" my hand on the front end, ust not at the pinky position. I always wanted there to be more there. The standard machined scales on my ffbm, the magnum machined scales on my fbmle, and the magnum hand shaped scales on my nmfbm all had the same issue of not having quite enough at the pinky position for it to feel right.


I'd like to think I have medium sized hands. Certainly not the bear paws some of the guys on here have. The TTKZ is kind of an upgrade/melding of both the ergo and fusion handles. This image shows what I speak of when I say that the pinky area isn't tall enough on the fusion handle, where it is more in line with the index finger position on the TTKZ. Flatter palm swell, less severe finger swell, a more even and taller ratio between the index and pinky finger positions. Less of a 'hard ball' feeling when you grip it hard. With the TTKZ my hand is applying relatively even pressure on every part of the handle because the distence between my palm and the curve of my fingers is anatomically correct. On the fusion handle, the distance between my palm and index finger is correct, but because of a combination of palm and finger swell, and then a less-tall pinky position, the bottom of my hand isn't applying as much grip force as it could. It works, but it's not as ideal as the TTKZ.

That said, it could be said that the fusion handle is designed to allow for a wrist snap, the smaller pinky area allows you to let the bottom of the handle float forward in your hand and then swing back when you close your grip. While the TTKZ doesn't allow that as much since the handle is so even and considerably taller at the pinky position, it's much better in a tight gripped chopping action.

This set of images shows one of the most (if not the most) severe 'ball in your hand' handle designs busse has done:

Note how much more severe both the palm and finger swells are on the KZII, the knife wants to roll in your hand like your doing a wrist snap. I like that the index finger and pinky finger positions are about the same, but the rear palm swell follows a lot of the trends in busse's handles of severe.

First impressions for any knife come from the handle .... and balance .... but the last impression is the handle too. Give a knife a solid days chopping and the handle dictates whether you could do a days work with it .... and whether "it is a great knife" ...

The TTKZ I agree ...." the best handle on a chopping knife done to-date".

My BWM LE ( once I smoothed the grips ) is a close second.

Of course there are the Basic handles .... nothing "basic" about them .... Jerry ought really to have called this knife range his "Professional" knife range .... not the "Basic" ....

There are few improvements I would like to see more than Jerry taking the overall dimensions of the TTKZ handles and getting a mold done for a Res C grip based on this.

Then do a run of "flat ground" Zilla's like on my Nuclear Zilla with that handle and using a skeleton tang and make the blade 11 inches to reduce overall weight ... with the skeleton basic tang it will still have the same "forward weight" feel of the present Zilla's and will be able to chop as well and be lighter to carry. Nothing fancy needed on the spine ... just a simple curve ... make this and you ought to have a Khukri lighter than the NMFBM and able to out chop it ... definately a dream knife for me and one which would earn it's greatness through the "handle" ...

You could do a similar task with the BWM grips ... and have a second handle offering for superior "user" knives where lightness and performance work really well ...

Definately a "way ahead" that would be offering knives better than any done before ... :thumbup:

Great post LVC !
 
LVC, I would say so on the hands, but we each do what we can with what we were given. Man, those MOABs sure look sweet, but they seem more like a short sword than a knife and are even heavier than the gladius so I have a hard time figuring out what I would do with one. Did you ever use that monster? Before I bought a Zilla I held both versions but the KZ2 and I couldn't come to an agreement with the handle even with the thought of a bunch of modding.

Peter, as usual you have some very insightful ideas there. :thumbup: I really like your idea for the TTKZ in res-c! :D Just as long as they mold it after the handle thickness on yours or the original TTKZ run as the pumpkin ones are a bit thicker for some reason and don't feel quite the same. Heck, I wouldn't mind if that was done with INFI or with diff tempered SR101 as a KhukRat. :p
 
I've never met the man in person, but those who know: How long is Jerry's index finger??? Maybe he's a mutant or something. ROTFL!
 
I used it to whack a 2x4 a few times. The edge felt overly thick, and it acted like the FFBM did, it was so thick right behind the edge that it wanted to crush the wood like a hammer more then sink into it like a knife. i don't know if the satinned custom shop ones are better, but if i purchased one again I would probbaly send it in to have the edge thinned. That said, the reason I ended up selling it was because of the price difference between it and the TTKZ, 2,100$ vs. 750$ for something relatively close in size is hard to rationalize unless you have the extra income. If I win the lotto it's gonna be the first on the list of purchases along with the gladius and ruck.

I'm gonna get another TTKZ and have garth redo the edge when I have the money. I had to choose between a lower cost NMFBM with the fusion handle or the higher cost TTKZ with it's awesome handle, and I decided on the TTKZ w/future grind modifications because they weigh about the same stock and with a flat or near flat convex grind and a thinner edge the TTKZ might end up being lighter, longer and with a better handle for me.

I'd love to have a straight edge knife with that handle, cause I think I'd kind or rather have the NMFBM's blade. I love khukuries, I'm just more proficient at a wider range of tasks with the straight blade. we'll see when i eventually get that TTKZ sent in :thumbup:
 
i wear a medium glove and end up having about an inch between the pinky and the inside of the curve at the end of the fusion handle if i hold it all the way up. i always found that handle most comfortable for shape if i held it all the way up, and extremely uncomfortable when holding it all the way back when chopping because the front of my hand would be at the widest part of the handle. i fixed that issue by sanding the top hump down quite a bit. it's now my favored handle for chopping
 
I feel like I have Hell Boy Hands :(

LVC, I hear you on the thinned out Zilla and the cost ratio. The TTKZ Peter has is double flat ground due to being fully nuked on the top and very nicely done for balance. It is the lightest and fastest TTKZ I have held. Most of the rest are still convexed and much heavier including mine. I think a full flat ground linen handled TTKZ would be very impressive user until a straight blade is attached to that handle.

I feel like I have Hell Boy Hands :(

Aww, Dave, it ain't that bad, but don't ever make a red kydex glove/gauntlet for yourself just to be safe. :eek: :D
