I recently bought a box of the "Wild Wargs" from GW's LOTR model range to convert and use as sabertusks, because the finecast models are kinda pricey and I've never really been a fan of em anyway.
Here's a quick size comparison against a butcher/SM and a high elf:
And here's the finished conversion!
This is probably the most greenstuff I've ever used, so the tails/fangs aren't super impressive up close. They do get the job done, though, and definitely help the wargs transform into felines. I used the plastic tufts of grass that come on each warg sprue as the furry bit at the end of each tail. I'll probably use some liquid greenstuff to smooth it out a bit and get rid of my thumbprints
They fit in perfectly with the other beasts in the ogre army... the almost look like miniature mournfangs with their warg-y faces
