It is not quite clear to which kind of knife the word actually refers to; the most common probably is the large whacking size knife ~25 cm blade length, some people also use it for the mid size utility knife of about 12-15 cm blade length of a certain blade shape. Many old ones I have seen are...

Last summer when the outside temps climbed somewhat high (for us) we had air conditioning on keeping the inside at comfortable 22-23 C. Our kitchen stove (wood) refused to light up, totally, pushing all smoke in, lots of it. I had to take the smoldering wood out and take them outside. I took...

Finland just raised the age of reservists eligible to be called for service. I am out of even that.

Shhhhhhh ... they haven't realized it yet.

During Cold War there was a story telling why Soviet nukes were typically larger than western ones. The missiles used were much more inaccurate so they had to use bigger artificial suns to achieve a kill on a point target.

I once handled a Ti divers knife, owner said that he sharpened it as well as he could. It felt kind of sharp but it did not cut well. Admittedly an axe does not work like a knife but I still think that steel probably has an advantage there. I think C_C is right that in many cases an axe head...

Surprisingly many, outside the red forest. Many wild animals thrive there. In the reactor itself they found some fungi that seem to like radiation ...

Nah, that's nothing, if it were unobtainium I could possibly be interested.

Barium sulfate is a very good gamma ray blocker which is used in x ray blocking applications. It also blocks some radio frequencies. Fairly cheap in mineral form. Also available in textile fiber form for protective clothing, much more stylish than Al foil.

The concept resembles aluminium sledge hammer.

"Lightweight titanium head with twice the yield strength of steel" At least this claim is non factual. Also it is not at all clear why a less dense material than steel would be better.

Caffeine in fallen leaves apparently prevents other seeds from germinating. Tannins in oak leaves changes the pH of ground preventing some plants from growing. Fallen pine needles are not a very good growth medium for anything. This from memory, I guess the list is a lot longer.

That fits what one sees, the bright area goes through the whole thickness which high probability means that the low carbon outer layers are totally missing there and the high carbon core has been 2/3 broken possible from the beginning. That is a starting material defect, the plate from which...

OK, from what I can see: rectangular section of the stick tang, the final break happened in the bright area on the left; brittle fracture with a few striations so it did not happen all at once but at least in a few stages. Then the strange part: something like shear lips on both long sides but...

I have to start reading all that. My aim is as mixed species forest as possible and if possible to find a half way stable configuration. The latter is nearly impossible here because of Norway spruce, it tends to conquer everything except the driest areas. In the south the present view is that...

No problem there, this really is a different subject.

In Finland about 101 % of forestry papers are industrially oriented. While there may be some I have never met a study of how to found or take care of a non_industrial_production forest area. I have my own experiment on about 5 hectares but it has been guess work all the way. Are there real...

Hmmm ... how have you found a place to sleep half way safely if your normal travel is rudely interrupted? My first thought is that it has gotten more and more difficult (if no hotels available).

After some changes in legislation there are reports that some 50 wolves have been shot in the last week or so. So far no reports on suspicious changes in species after death ...

Slightly convoluted but about par on this thread ...
