Funny thing is my dad see's it as a hunting knife off of his randall model 3 and 4. He thinks they look pretty similar (hard to disagree) as far as the upswept blade and everything is concerned. He is considering buying one (FINALLY!, I have let him borrow an AD for the longest time) because he just loves thumb grooves and most Busse's dont have it.
He picked up the HG55 LE and said "Finally they made one right", hahaha I rolled my eyes but he thought the AD should have had no choil and thumb filing he loves it otherwise. I see him getting one as he wont leave mine alone...especially the LE.
