I use an across-the-body purse because straps slide off my shoulder. This was OK when I was able-bodied because I had a free hand to keep pushing the strap back up. I found a small purse called the Terrace Shoulder Pouch at ebag.com. Putting the purse in front of my body keeps it out of the way when I reach forward with my cane. I have larger over-the-shoulder bags, but they stick out so far I look like a pregnant walrus. A smaller knife is on the left in photo above. I think it looks like an assassin's weapon so I use it at home to cut vegetables.
