SA OTF Xiphoid MK IV - Arm Mounted Blade

video SA OTF Xiphoid MK IV - Arm Mounted Blade

Single Action Out the Front Xiphoid Mark Four

This is the fourth xiphoid I have made. It's pretty simple, and works very well.
This is NOT meant to be from Assassin's Creed! Though I love the game, this is UNRELATED.
Made from a drawer slide, 5 bolts, 9 nuts, strips of homemade faux leather, 4 keyrings, wire, springs, and a ring.

Thanks to Nightshade for the latch design.
Thanks to NightHawk22 for the awesome song.
Thanks to SINZA for his epic forum, you rock!

is there any way you could make me one, i would buy it if you made it

Sep 24, 2011. 4:07 PMjumper17 says:

Could you post specifics on either where to salvage a latch like the one shown in the video, or how to obtain/construct one? Thanks. (P.S. What is that EPIC music played in the sped up section?)

I just cut it out myself from scrap metal. It's shaped like an L with a hook.

Any idea where you might have gotten your springs? I used 2.4 pound springs from home depot, but they turned out to be made out of crappy material- Stretched out like nobody's business.

What width draw roller do you use?

Jun 4, 2011. 10:29 AMcowscankill (author) says:

Umm not sure, all the drawer slides are the same width from the hardware store...

Jun 5, 2011. 2:44 AMmulletman6 says:

Ah fair - It looks like quite a wide one, so i shal have to have a look for a bigger one :)

I like it

some tips / things you could do different:
- have some sort of arm protector, that looked kind of uncomfortable with the bare screw/nuts against your arm
- have it to where you can stab and slash with out the blade retracting, because a real hidden blade can do that, so maybe have a locking pin that can be removed [see below for details]
[see above for unnecessary use of brackets with words in them]
possibly switch the ring to your ring finger and have a locking pin wire and ring on your pinky-finger. so somehow you could bring out the blade and keep it from moving when you stab, and you could also bring it back in when you wanted

I would buy a wholly completed one

can you make a retractable blade??spring loaded or motorized any will work for me

Mar 5, 2011. 4:46 PMcowscankill (author) says:

I can, though I can link you to a tutorial that has already been done well.

what could i use for the blade?

Feb 16, 2011. 3:10 PMcowscankill (author) says:

Anything... depends on what you have.

av just made 1 from shin gaurds havin a bit troulbe with the latch

fitting music

Sep 5, 2010. 1:29 PMlerickson says:

could you post more of the specs of the design for those who want to make it? - even a project for DIY purposes.

Sep 5, 2010. 8:04 PMcowscankill (author) says:

Specs like what? Everything is shown and described in the video.

Dec 24, 2010. 6:35 AMEwwieImp says:

It would be helpful though if you could put the exact things such as bolt size, length, etc.

Dec 24, 2010. 9:45 AMcowscankill (author) says:

I never designed it on specific measurements. EVERYTHING has to be adjusted according to materials and the wearer. The drawer slide is 10 inches, that is the only fixed measurement.

Sep 6, 2010. 10:50 AMlerickson says:

I guess your right- I will just try to fabricate it based upon video

Dec 21, 2010. 8:13 AMSarthex says:

i think this is the first instructable i ever favorited O.O
awesome job man

Dec 21, 2010. 5:24 PMcowscankill (author) says:

Thanks!

Sep 29, 2010. 6:46 AM11richie21 says:

Where can I get or how can I make the release "thing" (metal piece that releases the blade)?

Dec 16, 2010. 5:59 AMPerfectPantaloons says:

i think the word you're looking for is a "latch" and you could always bend some 8 gauge heavy duty wire to fit

Nov 28, 2010. 9:04 AMdeathbygrandma says:

you could just make it out of a piece of thin wood, it would work just as well and would be easy to replace

Sep 29, 2010. 1:38 PMcowscankill (author) says:

Just cut an "L" shape from a piece of thick sheet metal and make a "barb" on it, like seen on a hook.

Dec 14, 2010. 5:48 PMpkthunder says:

hey just wondering... i have been looking for instructions on how to make one of these. could it be possible for you to make a tutorial?
THanks

Dec 14, 2010. 8:20 PMcowscankill (author) says:

I wouldn't be able to do much besides another disassembly.

Oct 2, 2010. 12:27 AM11richie21 says:

Thank you that help! I made the piece and actually made one of these with a blade but i was going to ask how much tension your springs have? I used only one because it was around 11.5 lbs but around the same size as your larger spring. the spring I have makes it hard for me to put the blade back in :( Thanks

Hey hey it's me again I'm shocked y arnt u wearing
That cool :) t shirt great Ible do

Oct 11, 2010. 7:58 AMIneXtrikabul says:

Would it be too much trouble to make a tutorial for this thing? It's too awesome to not want to make!

Sep 16, 2010. 10:49 PMgreatnameless1 says:

How much should I expect to pay if I want to build one of these?

Oct 1, 2010. 1:32 PMcowscankill (author) says:

I paid about $3, because I had most of the stuff. I'm not sure how much it would cost to buy all of the parts.

Jul 21, 2010. 7:48 PMknex 711 says:

when it has a blade how will it retract automatically other things ive seen

Jul 22, 2010. 5:05 PMcowscankill (author) says:

Sorry, I do not understand your comment. Please use punctuation and complete thoughts.

Aug 19, 2010. 6:29 PMPumpkin$ says:

Hey CCK!! I love the design, it seems like retracting is the only final step, and I had an idea, you could take a Velcro ring, attach it to your shoulder, and run a cable down to the blade-deployment-mount (thing) and Extending your arm downwards could retract it and lock it into place!!
