I bought a Leuchtturm 180 Stamp Mount cutter

After using inexpensive paper cutters for years to cut stamp mounts, last week I ordered a Leuchtturm 180 stamp mount cutter. Here's a generic image from the Internet of what it looks like:



Overall, it's a pretty good design, but there are a few things I would ilke to change about it.

1. I wish the numbers and tick marks on the ruler were colored white, to make them easier to see.
2. I wish the clear plastic slider to the right could be locked in place, so you could use the cutter to cut multiple mounts of the same size without having to worry that the slider moving by accident.
3. It would be nice if the slider wrapped around the edge so you can better line it up with the notches on the rules

As much as I like using a paper cutter, most paper cutters that have a swing-out rules, have some kind of gap in the ruler between where the rules on the main cutter ends and the ruler on the extension starts.

The paper cutter was a cheap imperfect solution that worked well enough.  We'll see how well this works for me.
