Also: that's a super saw collection,, for dead lower Evergreen branches?
Few years I did professional landscaping; was able to get wholesale prices through my company. There was a Christmas tree equipment supplier with good prices.
{I got a solid shank, stainless steel shovel (made in England) from another wholesaler, then had a welder attach a stainless steel pipe to replace the too short D handle. What an effective tool, but will trash your elbows if reckless.}
Tree thinning in the American Southwest is an important thing. Firewood production is another. It is actually quicker for me to cut small branches with a pull saw than to use our electric chainsaw (easier on the back and better upper body exercise than standing there holding a machine)
Never owned a skilsaw or sawzall; just borrowed when needed. I would be concerned about accuracy pruning with a sawzall on high visibility trees but totally understand their usefulness for sure. First time I saw a sawzall on a remodel with lots of deconstruction, it was jawdropping.
Taking your most fresh saw and cutting near the ground will cause premature wear, that’s why I save the sharp saw for higher branches. Same thing with chainsaws; using a chain that needs to be sharpened anyways to cut low to the ground.
If it is a bigger log/tree that has been laying on the ground or the cut area has significant dirt on it, I will cut past the cambium with the older pull saw then finish cutting that bad boy with a sharp one. The time it takes to switch saws is worth it to me.
Sharp tools make for sharp work.
