I use envelopeners a lot and indeed prefer them to any other means of cutting paper in almost all cases. Here are some tips from my experience: Regarding the cutting tool itself: First of all, envelopeners are consumables: they will become blunt over time and there's not much you can do about it. Since they are cheap, simply replace them once in a while, ...

I haven't used this tool, but I have used loose razor blades to cut paper. The "getting stuck" phenomenon just seems to happen sometimes. I once grabbed a new blade that had a light coat of oil on it, and I had much better luck using it for a while. Assuming the oil had something to do with it, I sprayed the blade with some silicon lubricant and that also ...

These are normally slightly oversized (as is the example I linked), and may be sold under other names in places that don't use A-series paper, possibly with a different printed scale but the same ...

These devices differ from each other in terms of price, the size of media they can work with and the variety ...

A Tension Spring This prevents a guillotine paper cutter from acting like an actual guillotine. The tension spring is attached to the blade so it won't move by itself. A Blade Latch It holds the blade in place when you aren't ...

I have not used this tool either but there are a couple of conclusions that should be easy to draw. The tool is a fairly cheap one (in price not necessarily quality) so it would not be a stretch to think low quality steel or other metals might have been used. I would expect this to wear out and be more susceptible to damage then something like a craft ...
