Hi FP i only noticed your post just after my last reply, thats a neat trick with the photo, you get to see a bit more than in the previous light, it definately looks like it has been used to whack something, still weird how the marks on the xguard look a lot different to the marks on the grip! I would have expected whatever caused the marks on the xguard to have at least pierced the skin of the wood on the grip.
