I just tried a 1/2” and it barely fit.  Not sure if it reaches down far enough to sharpen. So maybe 3/8” or 7/16”

Stand! the ground's your own, my braves!
Will ye give it up to slaves?
Will ye look for greener graves?
Hope ye mercy still?
What's the mercy despots feel?
Hear it in that battle peal!
Read it on yon bristling steel!
Ask it, - ye who will.


Fear ye foes who kill for hire?
Will ye to your homes retire?
Look behind you!  they're afire!
And, before you, see
who have done it! - From the vale
On they come! - and will ye quail?
Leaden rain and iron hail
Let their welcome be!


In the God of Battles trust!
Die we may, - and die we must;
But, O, where can dust to dust
Be consigned so well,
As where Heaven its dews shall shed
On the martyred  patriot's bed,
And the rocks shall raise their head,
Of his deeds to tell!

I haven't heard of it. It isn't beyond the realm of possibility since grass-fed beef is something one can by, though. I don't, however, intend to eat any leather myself so I suspect for most uses it probably isn't any different than feed-lot fed or other leathers.

Happened to have an ad for a belt blank pop up from Amazon: European Leather Works was making a big deal out of their "grass-fed leather." Surely this can't be an actual thing!

That's a quality holster you made for him, Rube. Very nice work. I can see why he's pleased.

Thank you.
