Thanks everybody for your comments!
@ Eric and Col: it is a good idea (at least for me) to always have some tool steel around, just in case of the need of some kind of new, maybe special blade. For me, old files and sawblades are the best and easiest resources, I am not thinking much in recycling when using them. Although, of course recycling is always a good thing.

Of course, there is no tool you can not find on the Swiss Army Knife. It even sports a thickness sander (if you have the patience and skills

).

Thank you Steve, and no, it is not spruce (but almost). What you see comes from this stem, which is Silver Fir (
Abies alba) from the woods in the neighbourhood (a 500 meter walk away):
Silver Fir seems to have about the same stiffness to weight ratio as Spruce and, unlike the latter one has (almost) no resin pockets at all which makes it a highly appreciated construction lumber here around.

Thank you Pete!

Before making this "pocket froe" I also thought of some heavy knife like your bone cleaver, but then I just started to like the control this lever gives you when splitting the wood. I have a big and heavy froe (34 cm blade, 2 kg) which I use to split log halves into smaller pieces (for entire logs I prefer wedges). Using that froe I came to the conclusion that I would not like it very much handling that kind of weight on my "desktop" (= bench top, of course).

Too true!
It is really amazing what one can find within one tree stem.
Here, still the Silver Fir from above, I got a slight but still rather acceptable twist:
One meter further down the stem things got really wild, from just about the same twist as above in one half, to this:

Splitting such interlaced/wavy grained wood with a froe is close to impossible and it is better to use wedges, or a saw if one wants to make something else than firewood.
Sometimes there are very notable differences even within the same length and within the same quarter!
curly wrote:A handy trick i've been shown is to always spilt the billet into halves , getting progressively smaller , it saves getting splits that jump across the fibres .
By the way if anyones interested there's a froe on ebay right now , I think they called it a large shingle splitters axe , a froe it is .
Yeah, shingles... Have a look at this man, how he produces some of the nicest Western Red Ceder guitar tops - for roofing his house!
