So my DF is having issues trying to find a nice gift for his Best Man/Groomsmen. 
He definitely doesn't want to buy them a flask or barware.  It doesn't really suit the guys he would be giving it too.  He also doesn't want to give money clips (who carries cash around anymore?), tie clips, pocket watches, harmonicas, poker sets or man cave items.  None of these guys would use these items.
The only thing he can think of is a nice leather wallet but he is concerned it’s boring.  He bought ties, pocket squares and cufflinks for them when asking them to stand with him but we both agree that this isn't a true gift as they are required to wear them at the ceremony.
Any suggestions to what you groom is gifting to his men?
Thanks!
