I've been using my moras a lot recently and practising my knife skills, my hands look like I've been juggling broken glass but here's a simple tip to clean your blade out in the field
you can see the state of the blade, I really should look after it better, still
pick some horsetails, crush them and rub the blade
after about a minute you can see the silica in the horsetail has helped to clean the blade, even removing the patina
and after about 3 minutes rubbing.
At this time of year the silica in the plant is still quite low and it increases as the season goes on,thus increasing it's effective cleaning abilities, you can use it on your pots and billycans also.
