Many pro points - mostly centered on strength.
My biggest con - - any Tanto style knife I ever picked up was/is a chisel grind, with the flat on the right.
Since I'm right handed & hold things I slice with my left hand, that's right hand flat is useless - - worse than useless really since it slices everything all katty-whampass..
I guess a fella could hunt one down with a flat on the left - but - why bother when there are so many other knives out there to spend my money on.
Weird..I've never owned a chisel grind Tanto.
Cold Steel tantos are all double ground.
Many custom makers do both chisel and double/standard.
I have a few Cold Steel tantos and a custom.
I will say, the 1/2 serrated tanto Recon 1 is double hollow ground, but the main edge is nearly flat on the right side, while the left has more bevel. This is because of how the serrations are ground into one side.
Got two old ones. I've had these for 20 years or so.
Tantos are decent EDC knives.
The secondary point has its uses. It acts like a point for precise cutting, like a warncliff.
For years I kept the point distinct. Sharpening wach edge, and keeping the secondary point (yakote).
It aids in penetration on a snap cut. I've tried the same cuts with bowies and other curved blades and that angle acts like a point to focus the energy of fhe cut and to penetrate. Works great on clothing, fabrics and leather.
Some hate them. Some love them. Try one out, and see if you like them.
One thing I've found about the only real chisel grind I have is that when whittling wood, the curved (convex) side on the left side aids in carving as a right handed person. The flat being on the right hand side allows me to angle the edge to control the bite/angle of cut. When cutting with the flat side, it is harder, and the edge wants to stay at the angle, and gets buried. The grind being on the left and rhe flat being in the right works well for whittling, but vor cutting bread, or cheese, or other item I want a straight, flat cut, I want the flat side on the left.
I've forged a "chisel" grind on a blade, looming at the Yakut style blade. For a right handed person, they put the flat on the left, and convex the right side.
Here is what I mean.
Flat on the right side, convex on the left.
