image.jpg I made Rubys knife out of some spare sintra I had lying around and what to know what would the best way to finish it to look more like the knife on screen? It's a Christmas present for my bff who's a big fan of the show. Thanks in advance:)
 
I would round out the handle a bit more, rather than having the finger grips like that. Take a look at the pics I've attached for some shots to see what I mean.4x9_DemonKillingKnifeMain.jpg162461_1332022781011_full.jpgCasRubyKnife.jpg

Obviously, just from those three shots, you can tell that the handle on the prop changed many times. But it's always been more of an overall curve than a handle with finger grips.

For actual finishing in terms of painting, the blade should definitely be nice and shiny. I found a chrome paint from Lowe's that's their own Valspar brand that is shinier than the other two chrome paints I'd tested and also was able to be handled without taking fingerprints. Just let it dry for a long time after the final coat. I let it sit for a full 24 hours and still got a little bit texturing from the cloth I'd wrapped the item in where it got some pressure applied to it. It's fine now though (and was able to be handled without marring sooner than 24 hours, it was just where the pressure was.

The painting on the handle I'm less helpful on. I just recently sculpted and painted one, but I'm not 100% on the paint job. What I did though was lay down a base of the off-white color and sealed it. Then I used a foam brush to streak on the brown, which I didn't use a single color, I had different browns, some yellow, and some black on a piece of plastic that I would swirl and mix as I went to keep a natural color variance. Then I very lightly rubbed up the length of the handle in few places to show more of the base color. It's passable, but if I had it to do over, I'd change it up a little. Unfortunately I was under a time crunch and it was kind of do or die.

I'll try to upload a pic of the handle I just finished so you can see what I'm talking about a little more. Hope this helps!

. Thanks for the pics. The handle has been driving me mental. I've shaved off as much as I dare to now. I'm hoping it looks more correct/natural cuz I can't tell anymore.
 
Any tips to make the handle look more like bone/antler? I've read about clay but this knife is meant to be handed at cons and stuff. Thanks in advance :)
 
I finished mine a few months ago, to get the elk handle look you want to have three or four shades on your palette. You need an earth brown, a light brown for detail, a bone/creme for a "primer" and finally white to add more detail in the grooves. Will add pictures of mine tonight when I get home.

Thanks a ton for the tip. So you just made the effect w paint and not carving? What kind of paint did you use? Latex, acrylic? Sorry for all the q's but I'm trying to get this wrapped up for Christmas
 
I had initially molded my handle, in fact the knife blade is "screwed" onto the handle with a big bolt. For the texture you might need to look for pictures of antlers, like elk, or moose. Once you make the ridges you can paint the way I said before.
 
I had similar colors as I painted as well. I just didn't do the white details over the brown. That was more where my selective wiping came in. And also maybe where my slight dissatisfaction of my final product came in. Here's a pic of the handle original, before it was molded and then the cast/painted handle.

It's not so much about a layer of each color as it is working the colors together at the same time to create depth and texture. Like I'd mentioned from when I did mine, I had all of the colors out at the same time and was grabbing/mixing colors as I went. But not fully mixing the colors together, just getting them all on the brush, then streaking the brush up the full length of the handle. As the brush strokes overlapped, they naturally blended and created a cohesion of colors.

Also, since you cut the grooves into like you did, you can create depth by using a wash to create shadows in the low areas and/or some dry brushing to add highlights to create greater contrast and depth.

I like the way that came out. It looks really natural.
 
image.jpg A black wash really makes the details pop it looks so much better now the rub n buff is in the mail and that's what I'll just on the blade and hilt and this will be one sick piece of work
