Wolf, i've been using a helle trofe for a about 3months now and have found it to be very reliable especially for the price. Holds an edge really well and using a DC4 i have no trouble keeping it sharp in the field.
Used is for the first time a few weeks back for spliting and it held up to that with no problems.
I cant use mine very well for say pounding nettle cordage as the tang protruds at the end so that it can "clip" onto the sheath, but i dont think this is on that knife. Also as standard the spine of the blade on mine is a little too soft to be of much use with a firesteel so a bit of filing may be in order to achieve this.
All in all though the blades on Helle knives are imho of exceptional quality for a machine made knife.
Just be careful though....if you buy this ONE utility knife you will end up buying another and another and another
