Well, Ti starts to burn at around 800 C, long before it melts. I have also seen Ti tubing oxidize strongly at about 600 C, when it cooled down the scaling shot off in every direction almost dangerously, we all stepped back.

Yup fun stuff impact mechanics, it tends to run around linear or angular momentum, which is not energy. Linear momentum is quite simply the product of mass and velocity, m*v , which fairly fast shows that it is linear to both variables. That, I think is the important thing in this case.

I thought about that too but my own experience has been that speed does not compensate for mass generally. I have a light weight Roselli hatchet with slightly personal geometry and that splits ok, actually quite well, at the small end but suffers considerably when bigger blocks come out.

Mass is mass, Ti does not swing any faster than equal mass steel. Also the claim about energy transfer is such that it should be followed by something much more substantial. (The impolite way of saying is that it is BS with very high propability.) I am also sceptical about claims of Rc not...

Hmmm ... where should I start (aerospace structural and materials engineer), norhing wrong with Ti itself but a tool that partly relies on momentum to work properly does not automatically benefit from lower density. A slitting axe needs both a certain mass and thickness to work properly, a GP...

The good thing is that treatment is very apparent and easy to arrange.

As so often it also depends on anyone's definition of "bushcraft". Fishing camp is different from 4 day 100 km hike which is again different from ...

I think Mme Toddy had it bracketed, some times a hatchet makes life easier, some times. though not very often, it can be life saving. Often not needed at all. When trekking I look at the area, season and phase of the moon to decide weather to take one with me.

I went through that list and it is what I was looking for, Bibury apparently cheapest. I guess it is MIC but that is somewhat moot point in this case. Now I am trying to find somebody selling it locally. For some reason I am still not very comfortable buying from the web though the few times I...

At least two american pines are known to be toxic P. ponderosa and contorta. Norfolk araucaria is not healthy either and yew you all know. Here Norway spruce is used in making syrup and spicing beer, the beer is not bad.

Not if I am in a hurry and I am not certain she could do anything I could not. Some time since that happened and at the time I was certainly stronger than any *ess, the buckle was totally stuck, and finding the fastening was not that hard. Modern fastenings might require a tool to release.

I have an early "sun shirt" made from Supplex, fine PA fiber and thin weave, a couple of pants too. Works well and is very comfortable, dries fast. For some reason the material did not really catch and is rare nowadays. I am following with interest as I am planning a thin hoodie type shirt...

I am not going to take this into planes, it is for normal use while on holiday to be carried in checked-in luggage. Local legislation and enforcing is just so unpredictable that I don't like to take chances on expensive tools. I don't seem to have problems with binoculars but the bird book...

Roxon is a familiar name the other two not, I'll have a look.

I think I am looking for a smallish one with very basic functions, nothing like the LM I carry EDC.
