Yep the brother really didn't look after it will and that was part of the problem it was used all day and spent little time in it's plastic sheath. If the has oiled it from time to time there would have been less damage. We was also at sea on a boat for much of the day so probable a little extreme for bushcraft.
I was thinking of your Islay trip when i asked. Am I giving you an excuse to have another trip
.
I am looking for a good full tang bushcraft knife and this sounds like the prefect all rounder thats why I am ask about salt water.
Thanks Gary for the replies and enjoy the trip to the sea side.
