hope you ain't got bystanders when cutting grass, etc. ... them superhard blades lose an argument with a stubborn rock or steel rod and they is apt to be pieces of mower blades flying about like shrapnel... JMHO.

Seems he's just putting "hard surface" on them. The blade should still be as brittle or not as the original blade. 7018 isn't exactly a hard surfacing rod so it appears he's just putting metal on the cutting edge, then grinding that instead of the blade. Though i wonder about the heating effects on the blade body.
I'm no metallurgist, but have done enuff lab testing on mower blades to appreciate the strict engrg/safety specs involved relative to grain structure, hardness, ductilility, ad nauseum. The 90 degree bend test around a one inch dia rod w/o any cracks is tuff to meet all by itself.....

Main thing is, I make sure my yard doesn't have any steel rods or rocks in it, it works well for what I do, plus I don't run a small mower, 72" turf tiger

Here's a picture of mine. Big difference in weight and thickness I'm sure.

What size deck are those from? I don't think they have quite as much lift as mine but definitely look more durable.

They go on a mmz2554 54" cut. They are high lift. Very thick and heavy. They fit the 54 Tank and the 54" MTD Pro which are one of the same.

I have 2 sets so I usually sharpen both at least once a season. I still use the original set when I bought my Cub in 2003. I have a set of Hi-Lift blades and they work great with the triple bagger. Both set show no signs of cracks or broken off wings

I usually sharpen mine once at the beginning of the season.
But I am also using the gator G6 blades that have bits of sintered tungsten along the bottom of the cutting edge. So they dont dull very quickly. An I run over lots of dirt clods, mole hills, and sticks that I am too lazy to pick up. I also keep the trails in the woods mowed, so lots of twigs and sticks there too. All in all about 2 acres of mowing once a week.

I probably have about four mulching blades for my 33" Snapper Yard Cruiser, so it's easy to keep at least one sharp and ready to be installed. I change the blade maybe three times a year. I put a non-mulching blade on in the fall (I have a few of them, too), which is better for picking up the leaves (which if mulched get carried in by the dogs...).
A sharp blade cuts better and puts less of a load on the mower itself. I thinks it's hard to not change them too often.
