And I do apologize for no pic..but I'm too much of a noob to post pics..cuz it won't let me. ..but I will post some as soon as I am allowed..anyone know why I can't post pics? Is there some sort of quota? That I need to fufill?

Upload pics to an image hosting site such as photobucket, and link them in thread using IMG BB-Code, such as
. Pretty easy, and you don't have to upload anything to Bladeforums.

Out of curiousity, do you have a choil or no? A choil should move the balance point forward and make the SHBM feel more blade heavy as long as the balance point is already forward from the choil area... I think.

Mine is choiless which puts the sweet spot further back. Without the choil might make the blade feel even more "balanced" or maybe even lighter. All I can say is that this knife feels deceptively agile and versatile. :)

Nope. NMFBM wins. More mass further away from you hand equals more impact (given the same swing speed).

However, since the SHBM is thicker and heavier than the NMFBM it should about the same if not more capable to produce impact force closer to the tip.

SHBM is slightly thicker at the spine, and is flat ground. However, it certainly is NOT heavier than a NMFBM, which carriers quite a bit more weight out further from the handle, and is slightly longer too. The full-height convex grind of the NMFBM is much thicker for more of the blade height.

In other words, NMFBM is the better chopper of the two. :D

Hey All,

Just wanted to point out that the Anniversary SHBM "sweet spot" or rather the section that has the most blunt contact force is closer to the handle than the NMFBM. Now from my limited knowledge of physics this means that less human force is necessary to create the same impact force on a NMFBM. The concept is called "Conservation of Angular Momentum". I'll leave a link to explain this below. In real life application that means the Anniversary SHBM would be superior to the NMFBM is areas where less space is available thereby rendering a smaller range of swing motion. However, since the SHBM is thicker and heavier than the NMFBM it should about the same if not more capable to produce impact force closer to the tip. Ergonomics of the NMFBM make the knife feel more blade heavy. So although I am biased in favor of the SHBM -- I think overall physics and the handle style make it a slightly superior chopper. Anyone more educated than I am is more than welcome to point out anything I got wrong. Either way here is the link

Hi Rob,

Angular momentum is, to put it this way, a principle, so all bodies are subject to it regardless of its physical characteristics... so a rotating feather is subject to the same angular momentum than a railroadtrack.

What we should discuss, (and the article you quote, talks about) is angular velocity, and torque.

The angular velocity is the speed in degrees, an object rotating around a pivot point covers, in that sense, the further away from the rotating point the faster the object moves given a constant speed, something similar to the tires of your automobile, during cornering, the outer wheel covers a greater distance than the inner one in the same time, even though they both cover the same amount of degrees.

the torque in this case, is the amount of force that is put on a rotational motion. Imagine what happens on a first degree lever, the further away from the fulcrum, the greater force it can be produced.

So, for chopping, a longer object with the impact point located the further away from the rotating point (the wrist) is the ideal...much like an axe or hatchet

(MY SHBM IS NOT WITH ME YET), so I thought, the NMFBM, being longer and thinner, should be lighter and faster, probably, less effort on your forearm less massput in motion, and greater speed at the tip of the blade at the moment of impact.

On a ASHBM, I do not know how far from the wrist the sweet spot is located, and how heavy it feels, I know it is heavier, but since it is shorter, I don’t know the overall result of the chopping process, because the operator, comparing it with the NMFBM (which I do own), is trading weight for length.

Another aspect that I would like you guys to elaborate on is ergonomics, because, due to a proper ergonomic design, a heavier knife can feel lighter therefore producing less exhaustion from putting it in motion...

Thanks for your contributions Gents.

all my deffinitions are straight from memmory, so feel free to do any corrections.
 
Me three. Im not so sure that the ASHBM wouldnt bite deeper and be more efficient.

Thus making it a better chopper:thumbup:

TierraVentura,

I see what you're saying and I appreciate the input. My point was to say that in an environment with less space and therefore a reduced range in motion, a blade with the sweet spot being closer to the handle will result in more force output on an object in close range. The inertia that has to be overcome to swing hard on a blade that is very forward heavy is more than the inertia on a blade with the "sweet spot" closer to the handle. I could be wrong here but if Kinetic Energy= 1/2 mv(squared) then a blade with more mass closer to the handle will produce greater blunt force in a space where range of motion is limited.
 
Whoooohoooo :D i got mine today, i will be chopping wood tomorow and try to do a review but so far i can report that it's great for cutting beef :D.

It feels incredibly light and nimble for it's size, it's so light you can easily flick it with your wrist to take care of small branches or brush. I can't wait to chop some wood with it tomorrow.

Where is it that you guys are getting that the ASHBM weighs more than a NMFBM??? From everything I've read, the ASHBM is lighter by 3-7 ounces (26-27 oz vs. 30-33 oz).

What I think that everyone here is missing is that since NMFBM is heavier overall and is a bit longer and taller, it means it has a center of mass located further down the blade away from the handle. If for no other reason, given the same distance traveled under the same acceleration, the NMFBM will hit harder. I think this gives it the winning edge as a chopper (pun intended). Not to mention the extra leverage that the offset fusion handle gives when chopping.

Now if I'm wrong about which is heavier, that would certainly change my guess.

This.
Also consider this.
The thinner edge geometry on the ASHBM should prove advantageous on softer wood/material being cut.
I dunno. I'm hammered and Now I want a ffg 5/16 nmfbm.

Spyderphreak everything you said is correct. I have both. Although the NMFBM I have is #7 of 13. However I believe the specs are the same as a normal NMFBM.
 
I have not done a 1 on 1 but the shbm should chop better and not wear you out like the nmfbm. Just more efficient and a better all around blade. Very versatile. The blade geometry is better on the ashbm. Just my .02
 
After a LOT of back and forth, I decided on a NMFBM from the custom shop about a month ago. Might still pick up an ASHBM CG too, but we'll see. Can't wait to see a chop-off between the two. It'll be close!

I highly recommend it. Even if in a chop off it ends up losing, which it's starting to seem like the consensus is that it won't, it's still super agile and maneuverable. Either way, both knives are the closest thing to Excalibur
 
Also of note, as it is a current model, the value of the ASHBM cannot be beat!!! :cool:
 
Also also of note, a lot of the speculation is based on 1/300s, and the swedge will make a big difference.

I have an NMFBM around 0.28 and I'm going to get a ASHBM but I'm still trying to decide on options.

I have a CGFBM user too for comparison if it still hasn't been done by the time I have them all together.

Why will the swedge make a big difference? Do you really think the weight taken out will be that big of deal, what maybe an ounce? Also, wouldn't the swedge be a hindrance when batoning since it'll eat your baton faster?
Thanks.
 
In regards to swedge on the original 1/300...I found that the 1/300 was noticeably lighter and faster. Nothing overwhelming by any means, and the normal SHBM was a slightly better chopper.

I dont see any reason to believe that this will change in the newer ASHBM versions. The non swedged ASHBM with a little bit more forward weight should out chop the 1/300 ASHBM.

Here's the difference to me now....



THe original SHBM's were mostly all coated except for the very few that have seen the original LE's; much less even handled one. I dont think the 1/300 was ever an original satin release. Ive had a modified version but not an original.

The new 1/300 ASHBM is an inch longer, and much thicker so the swedge maybe partially responsible for the incredible balance that everyone is speaking of cause I dont think there are many of the standard ASHBM's out to compare yet. So, this is still really an unknown.

The new 1/300's swedge is a thing of beauty! These arent coated. The swedge gives it a lot of WOW factor. There was a group of us at KC that passed one around and there was a debate as to whether the swedge was hand ground vs partially machined and hand finished cause it was so perfect. Later, I had a chance to ask Garth, and unless I was totally wasted at the time which I dont remember; the swedges are all hand ground:thumbup:

The 1/300 has set the bar high in fit, finish,ergos, balance and beauty. It really excites me about what will be coming from the shop in the future:cool:
 
I think the lack of swedge on the CG or regular LE will make it significantly more powerful and less agile. Mathematically it doesn't seem like much, but you can easily feel the difference in your hand.

Some will prefer one and some will prefer the other. I'm sure I'd like both.

Also, batonning a swedge isn't that bad as long as it isn't sharpened. Several people on here even baton on sharpened swedges and don't mind it.
