What doesn't help is that the Jardipedia http://www.jardipedia.com/article_Choisir-son-secateur_139.h... seems to think that "by-pass" is distinct from " a coupe tirante" - it describes "a coupe tirante" but not "by-pass".

In the context of a pruning saw (Felco 600), "a coupe tirante" does appear to refer to a pulling - "pull-stroke" - action, but although it's part of the French description of the tool it's left out of the English name, where the tool's foldability is considered more important to mention.

Owen might have sawn off the branch I was sitting on. Following his posting, I found:

These do seem to indicate that, rather than "tirante" being about pulling a cord or strap to operate the blades, it is about the blades having a scissor action. This website shows "bypass secateurs" and "bypass loppers"

"a coupe tirante" indicates a "bypass" mechanism
"a enclume" indicates an "anvil" mechanism
"a cremaillere" indicates a "ratchet" mechanism

"pruner" and "lopper" appear to be to some degree interchangeable - in the US "pruner" seems to be used more for the longer-handled "pole" variety, "lopper" for the shorter-handled tool, and vice versa for the UK, though there doesn't seem to be a hard and fast rule. So there's no certainty the elageur here is the "pole" variety.

I'd suggest something like "bypass pruner/lopper", but unless you know what the tool referred to is, it's hard to be certain of the translation.

I can't really say for sure. the only thing i know it is used by a gardener in a residence.

If you don't know what it's used for it's very difficult to imagine what the translation could be. Is it for cutting branches off trees?
