Follow the wiggles of the grain. Also, the label usually tells you if its ash or hickory. what draw weight/length would you like? That will determine if you can leave it as is or not. If you cut it and splice, you will need a handle riser as it will not be thick enough there. Your best bet on a splice is to find another handle and splice two handles together. Now, all that being said, if its hickory, you can get away with how long it is now, depending on draw length. With a bendy handle you can get away with 25 inches draw just fine. I am betting on it being ash though, as that seems to be the most used for handles like that. Though the color makes it look like hickory.... But that grain... ahhhh I dont know.
