Sorry I could've been more clear. I have 250% H2H and so far I haven't seen bonuses on spears like the Serrated Spear, but now that I've started putting points in throwing, I'm starting to get weapon perks like Finisher and Hit the Gaps on the spears. There isn't a distinction if the perk is intended for melee or throw. Hope that was more understandable, and thanks for the responses.
Edit- I'll just have to mess around with the spears and see how they work I guess. Was just curious if someone had tried before me
