A fat trimming knife is usually a boning or trimming knife with a narrow, slightly flexible blade. The shape lets you slide along muscle, remove fat and silver skin, and clean up roasts, briskets and chicken without gouging the meat.
The six below are boning and trimming knives from established makers. We have not used these products ourselves, so confirm blade length, flexibility and handle material on the current listing before buying. Keep these knives sharp, because a dull trimming knife is more likely to slip.

Fat Trimming Knife FAQ
What is the difference between boning and trimming knives?
They overlap. Boning knives are usually narrower and trimming knives are shorter.
Should the blade be flexible?
Flexible blades follow curves; stiffer blades give more power on tough cuts.
How do I remove silver skin?
Slide the tip under it, angle the blade up slightly, and pull it along the length of the muscle.
How often should I sharpen?
Hone before each session and sharpen when the edge no longer bites.
The Short Version
For budget value, the Victorinox Fibrox Pro. For commercial use, Dexter-Russell. For student value, Mercer Millennia. For forged German quality, Wusthof Classic. For a secure grip, Zwilling Pro. For bold styling, Dalstrong. Whichever you choose, confirm blade length and flexibility on the listing, and use a cutting board that stays put so your trimming is steady. A steady, sharp trimming knife makes every roast and brisket easier, and handling matters as much as steel. Look for a handle that stays grippy when wet, because trimming is greasy work and a slip can ruin a cut.
