I do a weird self-denial thing where I don't reach for my favorite knife, a Shindo 170 nakiri, because I know exactly how it performs/how much I love it and so I try to reach for knives I'm less comfortable with or want to grow my skills on. Even though every time I pick it back up I'm smiling and chiding myself for spending money on too many big gyutos.
There's something about the Munetoshi 240 that really clicks with me though. It seems a little beefy but is one helluva cutter, can push or rock depending on my mood, has a deceptively thin tip, and it's hardly reactive. Despite my best efforts and loads of use it just refuses to take a colorful or strong patina. I chuckle because the Kochi 240 next to it on my rack is far more beautiful, has better f&f, a nicer handle, and is thinner BTE but I always reach for the Munetoshi over it.
Honorable mention is the Chopper King V-toku-1 small slicer, I don't get the joy from it that my other knives give me but the thing just works perfectly fine on everything I put in front of it and it usually just lives on my cutting board so I end up using it more than anything else, ARM just reinforced that habit.
