I just replied to your email.
I received the email, but no picture attached.
Most of the G10 Leeks have a flat grind, but a small few of the G10 versions apparently had hollow grinds - most of the other Leeks have had hollow grinds.
If you have a "good" straight edge, you should be able to put the straight edge somewhere between the handle and the tip of the blade with the straight
edge running from the edge to the spine (perpendicular to the linear edge of the blade).
If the grind is flat along with the straight edge, then it is a flat grind.
If the blade is hollowed out with a small concave gap under the straight
edge, then it is a hollow grind.
Sometime it is hard to show/see this in a picture. Hopefully you can confirm
with reasonable confidence which grind.
Please see email for more info.
Thanks.
