It combines the best of T grind and K grind in one.

What's up Mike!

So... In my humble opinion, the SM10 LB K Grind is a MUST have in my & your future bag, all year round ‍♂️
Not only is it a cheat code, in general, but for the most part in ANY/ALL types of bunkers (firm/soft/heavy or light). Particularly, "White Sand", aka "Tour Grade" or "Augusta White" Sand.
The LBK allows me to hit easier "splash-out" shots out of bunkers, per the unique 6° of bounce, versatile sole & ground. On that note, Its the perfect combination of "FEEL" and "TOUCH" interaction through the turf

........ Not to mention it's also a WedgeWorks Grind!! You'll have an ample amount of customizable options like adding EVEN MORE "Trailing Edge Relief" for fuller/square face shots OR adding "Heel Relief" for finessing shot shapes on tight lies & playability.

You convinced, yet????

Ultimately... It all comes down to playing style & shot preference; But, in the end we all want to be in the "players category."
Residing in the East Coast, b/c of the humidity & full four seasons, it feels as if I play on different course conditions almost every time. Incredibly, theres no reason for me to take it out of my bag!! Just have to adapt to the days weather conditions whether it be firm, grainy, or soft fairways and/or greens

Hope that helped, Bubba! Cheers!!
