Lots of options in this thread. I would trust a homemade tote, but depending on fabric, you might need flat felled type of seams with two rows of stitches that lock the edges of the pieces in. Bull denim or duck canvas might be the easiest. Strong nylon fabric and webbin is very strong too, but fraying and slippery, they need something extra to hold the seams in the long run. I don't have an overlocker and I sometimes have to fuzz a bit extra with edges and sturdy seams to get it strong enough.
