Which is better for hiking and backpacking?

The Kansbol. At 3.52 oz it adds little weight, and its stainless blade resists rust on multi-day trips.

Which holds an edge longer?

The Tops. Its 154CM steel has better wear resistance than the Kansbol's 12C27, though it takes more effort to sharpen.

Is the Tops worth stepping up to?

Only if you baton wood or pry regularly. For slicing, carving and general camp use, the Kansbol does the job with far less weight.

Which is easier to sharpen?

The Kansbol. 12C27 sharpens quickly on a simple stone, while 154CM needs more time and a good abrasive.

Which handle grips better when wet?

The Tops. G10 stays grippy with wet or gloved hands; the Kansbol's polymer is textured but slicker.

Both are durable. The Tops is built for harder abuse, but the Kansbol's stainless steel needs less care over years of use.

Morakniv Kansbol vs Tops BOB Fieldcraft Hunter

The Kansbol is the better all-round outdoor knife for most people: light, rust-resistant, and comfortable to carry all day. The BOB Fieldcraft Hunter is a heavier, tougher tool with a thicker 154CM blade and G10 handle, built for hard use and batoning. Reviewers praise the Kansbol's value and edge geometry; owners of the Tops respect its durability but note the weight and stiffer sheath.

Choose the Morakniv Kansbol if you want a light, rust-resistant fixed blade for hiking, camping and general camp chores.
Choose the Tops BOB Fieldcraft Hunter if you need a stout, heavy-duty knife for hard field use and don't mind the extra weight.
