Hi,
How do you want to carry the knife concealed? It configures to a wide variety of options. I carry mine on my right hip tucked in my pants with the safety clip on my belt (the clip has a catch that prevents it from slipping off the belt during drawing). I then cant it slightly to the right for easiest access.
The knife locks into the sheath either way, left handed or right, handles on or off. The scales are not G-10 but zytel patterned after textured G-10.
You can mount it horizontally, vertically, or inverted with either the mounting panels or the belt clip portion.
The main body of the sheath is approximately .37" thick at the outside curve, with it ~.62" thick at the mouth, where the retention aspect comes into play. There are 6 screws holding the body of the sheath together, and 4 vertical slots to adjust the position of the mounting pieces with their 4 screws (2 being used in the cross mounting mode). The slots also serve for mounting on the leg with 1" neoprene leg straps. The sheath completely separates and field strips for cleaning if needed.
You can use the belt loop, the BC panels for webbing, belts, harnesses, etc., tie wrap it in place, use leg straps, or with a neck chain for carry under the clothing.
The knife steel is AUS8, blade thickness is 3.8-4 mm (.1495-.1570"), mirror finished and then titanium nitride coated. The handle of the knife with scales attached is .390" thick with totally radiused edges. The newest ones will have serrations in both of the front finger grooves.
It's the most versatile production sheath design on the market as far as mounting options. There are no snaps or straps to mess with, and the retention resistance is adjustable to personal needs.
There is a sheet that's included with every knife that discusses the mounting options. If you contact me, I can email you a copy of these sheets.
The bulk of the current production of the tanto ABCs (model 2605) is shipping out for downrange distribution to the troops in the war zone at the present time but your local dealers should be able to get one for you. Retail price on it is $69.99.
Hope this helps.
Jim
