In the case of rust formation on your knife there are ways to remove it by using a rust eraser. Just wet the rust eraser and the knife and start scrubbing – gently at first – your knife using the appropriate grit rust eraser. Rust erasers are made from rubber and usually come in 2 types, rough and smooth. If the rust is a lot or persistent , start with the rough one and move on to the smoother one until rust is removed, putting baking soda with water can help the removal process. Never leave your knives with rust for an extended period. Rust will grow and penetrate deeper. As soon as you observe any rust formation, immediately remove it from your knife.

Another possible issue is cracks in the handle. With time, the wood made handle could present some cracks, mainly where the blade is inserted in the handle ( ferrule area). In case that happens either address to us for instructions and help or use a cyanoacrylate adhesive to carefully fill the crack before it opens and create water and bacteria nests. Be careful to use the CA glue on a dry wood/blade.

Patina is a form of “good rust” and usually appears as blue/yellow/red or greyish residue on the blade that doesn’t go away with washing. This form of oxidization is actually protective and prevents blade rust. It can be removed with the rust erasers and baking soda but, most carbon knife users love their knife’s patina (us too) and also try to find ways to enforce it and even make the best looking patina!

Sometimes due to extensive use or small accidents (like using the hard side of the sponge) may cause some scratches in your blade. These scratches that ruin the aesthetics of your blade are quite difficult to remove as they require finishing skills and knowledge. If the scratches are not deep you can try to remove them with a wet fine sandpaper (the grit number depends on the scratch and the blade finish, but usually we are talking about 2500-4000) by moving parallel with the blade finish and in one direction ONLY. If you used the right sandpaper grit, it will make the scratch look better or even disappear. If not, it will probably look worse than before! Scratches can be tricky and it is better to avoid them from the begining!

Broken tip is a very common knife repair. A slight miscalculation during cuts or extra force used when not needed may cause the loss of the tip. This can be repaired either by removing material from above (spine) or below (belly) the knife with a low grit whetstone and tons of patience.

Chipped edges also need patience as they need to completely go before sharpening the edge again. To remove small chips you can start from a low grit and go progressively to higher grits, or, in the case of big chips, you will have to flatten the belly of your knife by pulling the edge along the stone and when the chips are removed you are ready to sharpen it as usual!

In any case, if you don’t want to repair you knife you can always send it to us and we will return it brand new!
