On whatever surface or bag pocket I place it on/in.

Now whether I remember any of those places.... Lol.

My favorite general use one is in my purse, my favorite chunky razor style is with my camping gear, and my favorite dagger is on my outdoors bag.

No idea where my 30 others are and I figure I'll find them in some box or bag or another. I know I placed a few of the mid tier ones in different survival gear bags...
