Sure. When just holding it out there is no weight forward to torque on your wrist.
Do you think this is unimportant? I place it very high on a list of desirable features in a sword. The wrist can create extra snap at the end of a stroke but it is not free to do this if it is locked rigid due to high torque. The wrist also contributes alot to changes of direction and general maneuverability.
Not sure what you mean by an atypical 3 pound sword though...
Sorry. What I mean is simply that a sword with POB somewhere very near the tip, like an axe, is atypical. Even on a falchion POB is usually not all the way out near the tip.
.This is where I disagree. If your example sword balances behind the guard, what would happen if you held it in your hand and placed the tip on a scale? The scale would say it's weightless, right? But when you try to swing it, does it really feel like the blade is weightless? Can you swing it as fast as a pocketknife? It does not, because the center of mass is not what controls how the blade feels (the amount of strain on your wrist/body) during fast moves. The moment of inertia does. This could be easily demonstrated with a couple different swords- they could be the ame length and weight, with the same center of mass, yet handle totally differently
Right now, I own only four swords. Two have conventional POB, about five inches forward of the guard. The other two balance at one and two inches respectively forward of the guard. These are the only swords I have available for comparison. You may very well be right and you certainly have the documentation to back it up.
I'm sure moment of inertia is important. That said; In regard to otherwise well designed sword but with POB close to the guard: It seems to me, when you start the swing, it does not take alot of torque to start the pommel moving because it is relatively close to the hand. It takes more force to get the blade moving because the main mass is farther removed from the hand. The pommel helps get the blade moving faster. This effect is more pronounced in a sword with POB near the guard because there is less inertia to overcome. Think of Turner's own example of a short sling being easier to get rotating than a long one.
Next, there are fundamental differences in the way you'd move swords balanced differently. If the center of mass is out on the blade, when you start the swing, the blade will naturally want to lag behind your hand, and then you snap it around once your arm is up to speed. This way you can get the swing started without having to move the mass of the sword- it just pivots. On the other hand, if it balances on the grip (behind the guard), then the blade won't want to rotate when swung. You will be forced to swing it as a whole, or actively make it lag behind your hand with wrist action.
Maybe from lack of group reenactment practice; Maybe from not enough swords to play with this differs from my own personal experience. The last two swords I acquired were selected BECAUSE of POB close to the guard. The Angelsword: POB one inch and the Busse AK47 about two inches in front of the guard. Both are more responsive and rotate faster than my two swords with POB about five inches forward of the guard. Neither imparts hand shock.
Up to now, I was hoping to find a longsword with the right quality and aethetics and POB right BEHIND the guard, in the hand. Now, after Turner's article and this discussion, I am not so sure. I have been very tempted by some of Albion's beautiful swords but was bothered by the forward balance.
.Honestly, if I had known you owned one of these I probably wouldn't have spoken up. I understand it can be hard to look at things objectively when you have that much invested in a piece, both financially and therefore also emotionally. edit- I missed when you mentioned this earlier; I should have paid better attention
Thanks, but I am glad you spoke up, so don't worry about it. I would appreciate any criticism of any sword I mentioned and not take it personally. With one exception:
I must confess, hearing people b--ch about the price over and over is wearying. Back when I bought my Angelsword, they cost about the same as the average Albion sword now.
Compared to what?
Hits hard and maneuverable:
1. Compared to when I hold it near the pommel. you take this up in the next paragraph 2. Compared to my two other swords with POB farther toward the tip.
Re: Viking swords-
I do not think Turner was advocating small pommels at all. He was advocating pommels of the correct size. Some designs do require a fairly sizeable pommel to adjust the pivot points. I own a Windlass sword where the corresponding pivot point for a center at the guard is indeed well beyond the end of the blade. (I removed some weight from the pommel to help it out, but that's not the real problem; the blade is. The mass in the blade must be distributed correctly before you can fine tune things with the pommel.) It's performance is exactly as predicted by the article. My big bowie knife can out chop it. Have you tried finding the pivot points (what Cliff has termed the "dynamic balance point") for your sword? I would expect it also to be beyond the blade's tip.
Yes, the pivot point is definitely beyond the blade's tip. I still like the way it handles though; And there is no trace of hand shock on impact.
I could be wrong but I don't think he gives any computations to demonstrate his ideas about pommels. Maybe he originally did the math but describes it in words in the article.
I don't like the way he got on a soapbox making fairly obvious attacks on certain sword makers, in an article that was supposed to be scholarly. I take his slam agains the concept of "harmonic balance" with a huge dose of salt, because I have not had enough experience with that concept to say yes or no. However, several sword makers have used this concept predictably and repeatably to change the performance of their swords, and have seen the same things in original antique swords they've handled. So I'm not ready to embrace or renounce it either way yet. I don't like the way he handled the section on draw cutting. While I agree that the blade can't magically get thinner when drawn, it is true that cuts should be drawn when cutting skin and flesh simply because that's how those materials respond to the edge. Bone does not, but it should be blatantly obvious to anyone who has any degree of butchering experience, etc., that the blade glides through much easier when drawn.
But I do very much agree with his ideas about the pivot points, and wish I had read this article 15 years ago.
Yes, I think his ideas about pivot points cannot be denied. I just suspect there is yet more to it than even he has come up with so far. To me he is on strongest ground when he he backs up his theories with the way pre-obsolenscent swords were made.
To me, the low point in Turner's article is when he shows us a photo of an ancient sword hilt with the caption....."A tang on and authentic sword if the Lockheed Skunk works designed a tang. It would probably look much like this.".....Anyone who would say that must be pretty impressed with himself. I wonder how the ancient sword smiths would have designed a stealth fighter.
