I was given one of these for a christmas present

It was brought from ronnie sunshines (he was very helpful when i found the cord for stitching the sheath was misssing)
It was the 10cm Carbon steel blade with firesteel and sheath.
It came very sharp so care is needed when making!
The instructions were light on information as i was a noob, but I managed to do it)
I use it fairly regularly, either fire lighting (prepparing tinder and ingniting) or harvesting stuff.
I find it a bit too large for carving,but some time use it to remove large lumps of wood if my hatchet is busy else where.
I've had it for 7 months and not had to do any thing to the blade other than run it down a steel lightly to get it's edge back.
I was well impressed for the money, but have not heard any one else use these...is there something about them that the BCUK folk don't like...???
