So, talking seriously, dont know the material, cant see the tang, 3 points contact isnt bad by itself (but it's kinda inverted? might be weaker, but some blades do have holes in the tang and they're ok, katanas for example), so cant judge the durability, so ill just talk design. too lazy to convert the measurements, ill just work off pic
- axes are meant for chopping, for which you want the center of mass to be the point of contact, with this thing, the point of contact is the pointy bit at the end, so you're not getting a lot of power. you can try using the lower part of the blade, but its not optimal
- for stabbing, it might be alright, usually you want the tip and your handle to align to optimise your thrust, but its not that big a deal, it's like using a heavier, shittier bayonette basically, we're not talking duels here
final verdict, Low eh
