I did not wish to upset you folks. But built in obsolescence in user consumables is all around you TVs. Automobiles. Tools, I can remember when the simple screwdriver had just a straight blade but many sizes. But now look at the things more working ends than you can shake a big stick at, now a slotted wood screw on this side of the pond is classed as a restoration product. If gun makers could brain wash their customers to accept a guns life is ten years they would do it in a shot. Well Automobile makers and those fancy phone makers have convinced our youth that they need a new phone because the battery does not hold its charge as it did when new. But the SOBs are not fooling me for one minute to join in their let me sell you a new one old chap!!!
