Depending on how pronounced the swirl pattern is it could increase the sensation and make it more "bitey" not necessarily stingy. If the swirl is like a spiral ridge around the cane (like a raised barbershop pole design) then it would feel the same as a normal cane but has the possibility for different marks. If its like a square that has been stretched and rotated around itself then it could sting a bit more but again it would give a different marking pattern. Since in that style you have a pointed edge there is the possibility that edge will dig in more giving the biting sensation its not guaranteed. Also these "spiral" rods typically are thicker than their non-spiral equivalent which leads to a more thuddy sensation. The other fun thing about a spiral toy like that is if it is big enough it can be used for insertion and now THAT would be an entirely different experience!

Good luck and have fun with your (hopeful) new toys!
