i would suggest just a plain wood cane.before and then after i had a knee replacement i was using a hiking cane i got many-many years ago in Europe.i took off the metal tip,not spiked,and used it every day.by the time i was post surgery and really not needing it all that much i was still taking it around with me.it came in handy for just not walking but holding doors open,using he handle to pull stuff tword me, reach and pull yourself up using the crook to hold a branch or railing,pushing open doors and herding the dogs thru the kitchen door.it sort of became a extension of my arm and hand.i does not come off as a weapon of any kind as old guys have one everywhere,young guys can fake a limp if anyone gets too nosey.
