Ah thats unfortunate to hear! What wood was it? Some softer woods can compress more, causing more slippage. Interesting griptap idea @slothymane, might have to try that. I've used a bit of tape before (rolled into a little cylinder, sticky side out), works okay, but never feels quite as solid as a proper wood on wood fit
It was White Ash for the Ken.. I went through a tiny phase where the grain of Ash Wood just called out to me.. I put a piece of the sticky side out of a post it note rolled up under Sarado to help on slipping cups with my Rosewood Analog Ken(the only other one I’ve had that problem with) and it worked ok.. Rosewood and Ash are my only two experiences with slipping cups(and I know I heard you say on Nerds that Rosewood isn’t always Rosewood I guess..?) so maybe it is the softer woods
Yea, the factory that produces those kens just advertises them as 'rosewood', but the true name of that species is Ebiarra I think. For example, check these pics. True rosewoods are VERY expensive, if you're paying less than $100 for the ken its pretty much definitely not a real Dalbergia (rosewood) species. Thats funny the white ash did that though, ash is actually a fairly hard wood. The rolled up tape/sticky note/whatever method works decent sometimes
