Handle length: 26.5 cm
Blade width (height)
at base: 26 mm
at narrowest point (about 6.5 cm from base): 22 mm
at widest point (about 34 cm from base): 32
Spine width
at base: 9 mm
at 1/3 length: 4 mm
at 2/3 length: 3 mm
1 cm from tip: 1.5 mm

Again you see very dramatic tapering at first, decreasing by over 50% over the first 1/3 of the blade length, then a much more gradual taper to the very thin tip.

Here are the details of the handle, all measurements in millimeters. NB, the two wider rings within the two silver sections have a triangular cross-section; the 8 mm measurement is of the base.
Wow Mark
You went overboard with those measurements, both on the blade and on the handle.
Thank you very much

I have in the meantime decided to design my own specs while waiting:






I based it on my Japanese blades experience and then adapted it. Guess that for a 25 inches long blade these specs would be for a very sturdy blade without being too heavy. I would want the handle to be even longer than the 14 inches of the tang.
Would you care to comment on these specs of mine considering it will be receiving a differential heat treatment for a very strong edge and a flexible spine? Thanks

Let me not only thank you once more for the super detailed information but it would be interesting if you folks started to compile this type of information for a couple of different blades of each style of mountings so that maybe we can have some data on a possible standard of proportions of the main parts, such as the handle's pommel (so to speak) and the other end. Same should apply for the scabbards.

I think that perhaps we could find out if there is a pattern in there, some kind of proportion rule. Or if the rules belong to different ethnic groups.

There must be something there...

Edit: Ooops, I did post the 800 pixels size thumbnail. I don't understand why it is showing the 1400 px size

Antonio,
Why do you want to custom make one, when for half the price ( I guess) you can get an old and authentic one from e-bay? Most likely, it will even take you less time.

Thanks for your concern Ariel.

The reason is simple. I want do use this foreign made dha-lwe and the fact that it has my specifications means I always like to have an active participation on something that will then be mounted the way I want it. It is a designer thing here.
There are many, say... frequencies. One is the collector of Continental South East Asian weaponry, who focuses on Antiques.

That's not my case. That's why

May I have a couple comments?

Firstly, its tang 's totally wrong (unless it 's designed for practice) The traditional tang should be thick,triangle and not so long tang. It should also be upward to match with blade 's curvature.

Second, Blade's thickness 's quite fatal for its balance. Most of well balance blades of this type are thicker at their base and taper to almost nothing at the point. You can also find proper spine width in Mark's measurement.

Just my 2c

Thanks for your comments PUFF
I am not making a total replica, but a dha-lwe based sword.
Indeed I should have curved more the tang. But I'm sure with the instructions it will obviously get there.

I see... darn, how could I have not seen the weight problem and had such a long tang? Thanks

Thumbs up

Dear Antonio,

That is a great design! I can't wait to see how you treat the fittings.

I echo PUFF's comments about the tang, but I see why you want to make it a full tang. I do suggest making it clear to the maker that the tang needs to continue the curve of the blade, at least somewhat (usually the curve of the sword is not uniform, but increasing a bit toward the tip, so it does not need to be an arch of a circle). It might be possible to taper it a little both in width and span without weakening the handle, too. Though it is traditional, I don't recommend the small triangular tang unless you really want to copy an old blade. Though it has a function (it makes the handle vibrate less, makes it easier to tighten the blade in the handle when it loosens with use, and makes it easier to change the handle), it makes a pretty unstable grip overall if you are not using the sword in the traditional way(s). I think the proportion of the tang to the blade is good (assuming a full tang).

I think that some of the balance problem of the blade can be remediated by using a "double taper," with the taper more dramatic near the base of the blade. As you will note from the measurements of the antiques, the spine at the base is very wide (generally a half cm, or a bit more), and it tapers quickly to about half that over the first quarter or third of the blade, with a more gradual and uniform taper after that. It makes for a graceful sweep when viewed from above, and adds greatly, in my opinion, to the grace and beauty of the sword. I suggest 6/3.5/3/2.5 rather than your 6/6/5/3.5 (I am assuming those are the measurements at the start of each section), with the final taper going at the tip to essentially the width of the blade edge as you have it in your design.

To further help balance, I think that you may have to counter the weight of the tang with a heavier ferrule section next to the blade. It would add to the overall weight of the piece, but I think the balance and feel of the blade would be close overall to that of a dha/daab. The point of balance should only be around 7-8 cm,a t most, from the base of the blade (they are very light at the tip). Oh, and the square tip itself has an edge, the spine width at the tip being essentially that of the bottom edge, making for only a very, very slight taper from the spine to the bottom edge at the very tip, rather than a typical triangular cross-section. It looks like from the design that you have incorporated this feature, but I thought I would point it out, has I didn't mention it before.

Finally, I don't know how closely you want to match the side-view profile of the blade, but if you look closely at the profiles of mine, and at the blade width/span (edge-to-spine) measurements, you will note that there is a slight "waist" or narrowing of the blade at the beginning, the narrowest point being near the point of balance (I think this would also help balance, by the way), than the gentle flare toward the tip. This is characterist of Tai blades (Tai, Lao, Shan, etc.), and it adds a further touch of feminine beauty and grace.

Mark

PS: regarding fittings, the wide bell-shaped ferrule at the base is often polygonal in cross-section (I forget the number, but I can check), though sometimes it is circular.

PPS: I have been tabulating these various measurements to see if I can detect a pattern, but I have let most of my research idle this last year, unfortunately, so it is not yet complete.

Thanks my dear Mark, but it's really just a variation. I will be planning to do a hybrid design respecting all the fundamentals though.

This one blade is destined for cutting hard targets so I place security first, hence the construction having two pin holes and a long tang.
I did increase the tip curve upwards in the spine, but I want a harmonious curve in the edge side. When you see an outline design like this it may fail to show, but using Illustrator CS2 I usually draw an elipse for the blade curve and then define the curve approximately how I want it.
Then I drag a guideline and cut the curve at the tang and move the cut area down so, although it doesn't look like, it is curved, not so much visually but it is curved. I guess anyway I will draw it again.
For a contemporary inspired blade I would prefer to have a strong blade.

Thanks Bro, I guess I will be designing it again, just to be sure its quite clear.
Grazzie tanti
