Sandpaper on edges of bat

I have a donic bat and since I use the penhold grip the edges of the handle hurt my fingers. Is it okay to use sandpaper and make the edges of the handle more flat or will it effect the bat?

Thanks for helping me out, its been 4 months i’ve been playing table tennis and i have improved a lot.

Hi Salar,

Yes it is fine to use some sandpaper to rub off the sharper edges of the bat.  It won't effect the balance of the bat much at all.

Greta to hear that you are improving.
