Digital calipers

I have this Harbor Freight Pittsburgh digital calipers. Their cheap, but for my purposes they do the job. However, there is this annoying gap at the very tip of the lower jaws for outside measurement.
Without any expensive tool is there a way of closing this gap? Perhaps using a wet stone or a fine file. I seldom need to use the very tip. I mostly use the upper section that does mate neatly. No, Im not buying a more expensive one. I just dont need it. Just looking for suggestions.

I believe that would destroy the accuracy of the internal measuring jaws because you would create an overlap.

I think weld the tip and build up the missing material. Then file/grind/hone the tip back to the proper shape. Precision work can be done by hand but it's slow, careful work.

You're probably correct.

As long as you measure from the same location of the caliper it should give you a correct measurement.

Option: Buy another one from HFT and then return the bad one.

Don't temp me. LOL
It's over a year old and truth be told suspect they're all the same.

I would not consider welding due to the great possibility the thin steel would warp and ruin the caliper. Also, unless I have a welder and surface grinder to repair the caliper, the cost of a new caliper is nothing compared to the cost of a welder and surface grinder or outsourcing these operations.
