Maarten is producing longsword and arming sword indoor training tools, to save your ceilings and light fittings.

I got to handle these at Swordfish...everybody there was really impressed with them. I'll be ordering one or two.

anyone handle the Indes sword? it states that in a thrust the blade slides into the grip. Interesting if they can pull it off properly.

[Mink]

Heh funny, we had discussed just such a thing way back... Good to know someone is doing a proper product with the same sort of principle!
have long wondered how objects like that would really feel and if we would not miss the visual feedback of the tip position. Hopefully I'll be able to test these for real now

Assuming it is the one I saw at Fightcamp it is surprisingly good. There were some issues with robustness, but that was some time ago...

[Monster Zero]

I'm going to be ordering some.

Matt, for Fiore, would you suggest the version that has the POB 6 inches from the guard or 3 inches?

I remember on your Vickers sword and mine that it was closer to 5.

[admin]

I can't speak for Fiore. I personally prefer longsword POB around 4-5 inches. I'd go for the 6 inch one, as it's a trainer after all.

[Monster Zero]

Thank you!

[John H]

also note that it says centimeter not inches. so as far as I am concerned get the furthest out they have. The single hander is only clocking in at 8 cm or just over 3 inches. The longsword is 3 or 6 cm, or just over 1 inch and just over 2 inches.

[Petter Brodin]

You guys say inches, but on the web site it says centimeters, so the POB is much closer to the grip than what you're discussing.

Silly americans mixing up their measurement systems...

[Dave B]

Not just Americans. I was born after metrication, but before it really kicked in.

Longer distances are in miles, speeds are in mph.

but heavy weights, which I tend to deal with at work in construction, are in metric tons.

My weight is in stone, and my food is in lb's and ounces.

I work at home in inches and at work in meters and mm, and load guns in grains

And when I was kid my dad told me that the french had 100 minutes in an hour and 10 hours in a day, and I believed him.

I'm confused.

[Hindmost]

I handled one of these last weekend and really really liked them. It's perfect for office breaks and long boring work conf calls I think. I just ordered one (the 6 cm one).

[Dave Long]

so ... how closely do indian clubs match the dynamics of tulwars?

[Chiron]

Do you mean American Indian clubs or India indian clubs? If you mean american indian. I remember handling one of Jay Redhawk's clubs and it handles rather differant the weight is all at the tip and the handle itself is a bit whippy.

Gotcha, sorry about that, looks pretty interesting though.

[Dave Long]

Thanks, Matt.

Just to clarify a bit: although the main purpose of a curtailed simulator is to avoid emulating Zenemon Yogo, it's also far more important that the moments of inertia at the hand grips match a full-size sword than than that the distance of the balance point from the cross matches*.

While it's obvious that the heavyweight indian clubs (or their persian precursors) don't match swordlike weapons, I was struck by how much the moulinets in lighter indian club routines resemble those in shaska dances: might the indian club have been the equivalent of the mblades swing for indian sabres?

Actually you need weight, center of gravity and moment of inertia right if you want to replicate the feel and performance. Based on the diagrams here on the bottom left Maarten takes them all into account (as yould be expected from an engineer I figure ).

Maybe I'm dull this evening, but I'm afraid those diagrams don't say anything to me...

I'm certainly willing to believe that Maarten matches the first few moments of the mass distribution exactly, but just wished to point out (for those who were concerned that the COG's offered on his longsword swing might be a bit close to the hilt) that if one has to make tradeoffs, better to make sure the second moment[0,1] matches.

As pointed out earlier[2], with slightly different vocabulary:

Dynamic length and blade weight are the two key limiting factors for the performance of the sword. ... Cross weight is less important for instantaneous perception in my experience ...

[0] matching golf clubs is also done in order to maintain a similar swing feel across a range of lengths, currently by moment of inertia/radius of gyration, and historically by a heuristic approximation.
[1] does the choice of axes matter here? (désolé vincent, j'ai pas bu mon café !)
