Has anyone dealt with a stuck coupler on an Awesomesauce or other high end aluminum hilt? The coupler is stuck on just one hilt. The hilt has sat for awhile untouched and the coupler has been on for years. In fact it was never removed after I received it, so dirt is unlickey to be the cause. I am thinking the time and possible temperature changes. I have read in other threads that WD40, heat, tapping it, strap wrenches would work. I just want to confirm that these are all viable options without damaging the hilt threads or the finish. Thanks for your help!
