Not as old as my Grandfather's ancient selfbow or his first year Kodiak Magnum, but my oldest osage selfbow is around 40 years old. I no longer use it for big game, but I use it now and then for small game. Don't use my Grandfather's bows anymore for fear they'll break.
This is my modern high-tech laminated longbow I've used this last decade. It's my main bow for everything, except for bow fishing. For that I favor my 20 year old Critter Gitter.
