Here's a pic of my Cold Steel Blackthorne. I've already used it a couple days and even went through a security checkpoint with no questions too. My ankle wasn't hurting anymore, but I just wanted to walk around with it.
I put a 7/8" rubber cane tip on it. A recommendation online said they put a 1" cane tip, but in the store I found the 7/8" to be a snug perfect fit.
My hammer cane is in UPS transit scheduled to arrive Wednesday.
