Okay, having now bought the DVD instead of renting it and never having time to watch it, I now have some new understanding of this sword's details. You are free to correct me on anything I get wrong. This is just what I see when I watch the film.
Pommel:
1. Has that nut and washer assembly at the end. Not seen on most replicas, even the DT.
2. Seems to have a flat finish rather than the SHINY plated look on most replicas.
3. Shape and notches differ from most replicas.
Handgrip:
1. Is a little shorter than most replicas.
2. Has a baseball bat's upper portion shape rather than a thin skinny rod shape apparent in most replicas.
3. Leather is dark brown and is smooth side out (Sorry for assuming fuzzy side out ONLY all this time. But I swear I've seen an official BH sword with fuzzy leather.).
4. Handgrip is rounded/oval shaped in some models and on others it is rounded on the sides and flat on the front and back.
5. Has ONLY the two front grip rings on all screen used models, and the rings are thinner than most replicas.
Crossguard:
1. Width varies between different props, but averages a little wider than most replicas.
2. Stunt swords have wider crossguards for safety reasons.
3. Like the pommel, it has a flat finish look and is NOT plated.
4. Is relatively square shaped with two little notches on each end, unlike most replicas that sport either the round ball shape tips or the clover shaped tips like other claymores.
Ricasso:
1. Length varies between props but averages MUCH shorter than most replicas. The shortest ricasso sword is featured most (most prominently at the end when it is in the dirt after Hammish throws it. My favorite music in the film BTW.) and is the choice length for the DT.
2. The ricasso is usually shorter than the handgrip in the film, not longer like on most cheapos.
3. Like the handgrip, the leather is dark and smooth.
4. Stunt swords have the longest ricassos for ease of handling in the fight sequences.
5. Grip ring varies in thickness between variations but seems to be thicker than the handgrip rings and seems flat, not rounded like most replicas.
6. Doesn't seem to be attatched really well (As seen in one of the battles in that eyesore of a shot. How is this thing attatched to the sword in the first place?)
Blade:
1. Varies in length throughout the film, but is mostly shown as VERY LONG (60"+ like LZ's sword and the A&A replica).
2. Has either an entirely flat cross section or a flatened diamond cross section depending on the variation. Most replicas choose the diamond shape but inaccurately show it off more prominently.
3. Stunt swords have shorter blades for easier handling in the fight scenes.
4. The shorter blade, long ricasso look for the stunt swords may have been the inspiration for the cheapos on eBay and other sites.
That's all I have to say about that. Feel free to correct me with reasonable evidence if I'm wrong.
