I go thru tape measures with suprising speed. I'm a bit rough on them, but the primary cause of the quick demise is the shoddy quality of construction.
I just purchased 2 Stanley lever locks, and one of them is already in the trash. Within 2 days of use, it developed a nick in the edge of the blade which quickly led to complete failure of the blade. Into the trash bin - $9.00 down the drain.
The biggest problem I have with tapes is keeping the good ones separate from the crappy ones. For cabinet-grade work, I really need a tape I can trust. As soon as a tape gets dropped, there's a real risk that the tang will get bent and affect the accuracy of the tape. I'll take measurements from the inside of a cabinet box to build drawers. The drawer slides I use require a 1/2" space on each side of the drawer box, but I've discovered they work best if the actual number is 33/64 (or 1/32" additional reduction in box size). On more than one occasion, I've been known to toss a tape in the garbage after realizing that the inside dimensions I took with the tape were accurate, but the outside measurements were just a tad short, result of a bent tang.
The new Stanley's have a feature that I thought I would like - the tang is shrouded by the front of the locking lever. Good - drop the tape, the tang is protected. BAD - no exposed tang to do a one-handed hook onto a board as I'm sliding it across the chop saw to set up for a cut. I have to release the board and extend the tape a bit with my free hand. Plus, they removed the switch that can be used to disable the lever lock, which I never liked. I like the automatic locking feature. However, they seem to have reduced the strength of the spring holding the lever, because all it takes is a little pressure and the tape is retracting. A real pain when I've extended the tape a foot or so for a quick on-site measurement, and the simple act of holding the tape firmly enough to take a vertical measurement causes the tape to retract...
I bought a very expensive tape the other day, and it will stay in the tool box for ever. A Bostitch 25' exta-long-stand-out gizmo I'd seen advertised somewhere. About $25 for the tape. Tape is hugely wide, and the extra arc they put in the tape to allow it to stand out so far makes it very hard to use. Plus, the spring is so strong, and the new fancy-dan tang that has hooks for every angle imagineable weighs like a pound itself, that if you're not careful, an uncontrolled retraction from 10 feet can take your hand off at the wrist.
I do remember years ago being able to buy replacement blades for tapes. Back before the day of the digital-read-out, my dad's machine shop used tape measures to do layout on items in the lathe. They had an 8' Starret machinist's ruler attached to the edge of a bench as a proving standard for the accuracy of tape measures. Before each job, a machinist would check his tape, and if found wanting, would get a replacement blade from the tool room. That new blade would be proofed too. Sometimes they were dead-on at <5', but after that, the marks would begin to creep off the line.
I'm going to look into the Komelon and Big Johnson units offered.
I do have one other tape that I thought was a good idea - from Fastcap, a company usually known for great ideas. It's a tape without an arc. Completely flat - supposed to be great for cabinet work because you don't have to roll the tape over to get a good bead on the measurement. Guess what else it does? Refuses to be extended by pushing the tape outwards. Measuring a long board or across a piece of plywood requires you to move to the end where the measurement is to start and hook the tape. Yet another tool to line the drawers of the toolbox...
