I've only really found the borgiablade to be useful right at the start. If I do "Tales of a Sea Hawk" with stormy start, there's a reasonable chance of having a borgiablade right away, which is useful when I'm trying to hike to whichever town is nearby and run into a bunch of brigands. At that level you only need to hit them once, then keep blocking until they die of poisoning. A few levels later it's next to useless but by then I've picked up something better, either from a dead enemy or lying around in a dungeon.
In my current game I've found quite a lot of them, but then I'm now level 25 and the game has been going on for a good while. I've found almost as many thieving knives as borgiablades. I'd probably have had about that many borgiablades at this point in any previous game.
