Can I grapple with Bite+arms in one attack?

Page 6, "Nonhuman and Superhuman Grapplers," and page 7, "Calculating Grip ST," are the relevant bits. An Trained ST 10 character grappling with both arms and the mouth* would have functional Trained ST 14. This is because you work it out by combining BL, then determining effective ST from that - ST 10 and ST 10 is BL 20 + BL 20, for BL 40, which is just a touch above ST 14 (BL 39.2).

*Grappling using a bite might not benefit from Trained ST from sources other than Brawling, unless you have a Perk to let you use, say, Wrestling for bite-based grapples**. Also, while Technical Grappling gives the bite the same ST as using both arms, it might be more appropriate to use relative SM like in Martial Arts - having the same SM or being smaller than your target would count as a one-handed grapple, for 0.5xST, which combines with ST 10 for ST 11. If the target is smaller than you, you use 1xST, for ST 14, as above.

**Personally, I simply allow for a single Perk per skill, called Beastly Combat, that lets the character use non-standard bits - teeth, claws, tails, etc - with unarmed skills that don't usually allow such (like Karate).
