For the swords, Christian Fletcher
http://www.christianfletcher.com/Christian_Fletcher/Welcome.html can make you pretty much anything you want, however he seems to be booked until the end of the year with custom commissions, which is great for him, bad for us
beyond that, I personally think Baltimore Knife & Sword
http://imakeswords.com/falchions.htm can fit the bill for Altair's Syrian sword. I too, really would like one, it fits my Iberian persona to a tee. This is another one he made, looks to be more of a two-handed type but the blade is almost spot on and the hilt shows the detail he can achieve
and I'm a fan of them, have been for quite a few years. Basically I love their blades for re-enactment work because they're so stout and nigh un-breakable.
Sir Edward,
Yeah, to me it's sad. I remember when Master Replicas had some really nice stuff out there, now it just seems to be mass-produced plastic and pretty much anything I've seen Assassin's Creed related (I held an Altair sword), just is bleah, it's functional, but the details and such are missing. The one I held had it's hilt's "wrap" if you can even call it that, already peeling off.
Also as a fun little twist to ruin the illusion and such with all those kits, the weapons, are all FOAM! Like blue, insulation foam! I have found personally that using foamies on them can add quite a bit more detail, but for a 10 foot rule SPARTAN, just the blue foam works great.
most of the events we go to, we can't have anything heavy, or that can actually shoot anything. Which is a shame, because I loved being a part of the Treckies trying to take on the Star Wars troopers and Mandos. LOL then the HALO Spartans came in and dominated all with their nerf guns, but alas, it's no more now. The tricks used can make some pretty believable melee weapons too, just in case y'all ever go to an event that won't let you take your sword in, just take a foam one
