I use this https://www.amazon.com/dp/B07TP7L6JM?ref=ppx_pop_mob_ap_share and I can carry it with the strap like a messenger bag, or I can put it in my backpack if I'm carrying more than just my knife roll. Usually I just wear my apron that has big pockets when I'm commuting so I rarely need a backpack as well. But idk how much stuff you carry.
