Best blade for "living" wood - buy recommendation

I have carried out with this blade different cuts. On the one hand it was taken to free a tree root, simply to shrubs and small trees to cut back on the other. I had various other sheets in use but none went so well by the surviving wood like this leaf. As a tool I have a Bosch GSA 10,8 V-Li cordless reciprocating saw from the blue line.
For longevity, I can only say that it has coped well the one time or another in the ground without being directly blunt. Get me this sheet Buy definitely be back when I someday run out the 5 leaves of this delivery.
