Je vois mal, sauf suite de dérapages imprévus, un changement de cap de l'Iran: les mollahs tirent leur pouvoir sur leur peuple de l'exécration de l'ennemi constitué de "l'entité sioniste" et je les pense trop intelligents et cyniques pour renoncer à cet instrument difficilement remplaçable...

To complement my previous message, the skill in using a manual tool does not consist primarily of some kind of virtuosity, but above all of a good appreciation of the capabilities and limitations of each tool and the skill to choose the most appropriate in each situation. It is to put...

I know, you still have to have the ability!
There is what is desirable and there is what is possible...

Concerning pruning hooks, there were all sizes, with various shapes, depending on the needs. At least at the time when local tailors made these tools by hand. As a young teenager, I had rebuilt a very light billhook which I use again for symmetrical reasons...

A good billhook, as you say, oh Christophe is in fact better suited than an ax for small branches, but contrary to what your friend says, it is made to cut and not break; and the green cuts much better than the dry...

You're becoming very touchy, Christophe! I had misjudged the scale of your project, but often enthusiasm for technological solutions moves away from simpler methods, which are nevertheless perfectly appropriate for limited work. As for fouling due to the burning of softwoods, this does not...

If I judge by the photos you produce, Christophe, pruning branches does not require the kind of "nail clippers" that you use: an extension pruner would do the job very well, and probably more quickly...

If you look into the matter a little, you will see that a harvester that operates entirely on hydraulics has large capacity coolers. And, again, performance varies greatly depending on the application.

The performance of a hydraulic device depends on its application: at low speed and in linear movement, it is interesting, in rapid rotation it is very mediocre, but is justified in certain assemblies for the flexibility that it allows. In short, a matter of compromise depending on the objectives...

A common mistake among amateurs (or even more if affinities!) is to push the file downwards. As a result, the angle of the leading edge is modified, or even left blunt, and material is removed near the rivetings, which causes the chain to break when it is often only at m.. .
