ok. your question tanto or spear.
sori i have many spelling mistake cos i am too lazy to retype it. ok
tanto and spear.... which one... hmmm
ok i am a very mechancial guy. so i wouuld recommand u which brand or model.
one of your friend posted tis...
'Hello! Generally speaking, a spear point will be better gor the general utility chores you described. Curved tips are useful for other things than just skinning. Pick the Tanto if you think you'll be doing some stabbing into dense materials. Or, pick the Tanto if you like them. otherwise, take the spear point ''
'he say tanto for some stabbing into dense materials.. but wat about spear point. spear point can stabbed into dense materail too
ók, i give u a very powerful yet easy mechanical formula. this formaula is used calucate how share your blade is or wethere if the knives can be stabbed into a surface ( provided the knives blade is harder than the surface)
the formula is Presure is equal to force over area. P=F/A where P is the Pressure, F is the force and A is the AREA
so i will explain one by one.
P (pressure). the hight the pressure meaning more force. in order words (to make it more easy for u to understand) if the value of the P is very high, it says that the knvife is very very sharp. if P is low, then the knife is not sharp.
F (force) : the force u applied. such as your swinging force. your chopping force. ( i will put tis value as a constant, meaning i will not change this value. so i put it 10 kg of force)
A (area) : the cross section of the cutting edge or the shape of the knive.
look and the formual again P=F/A. i will put the value of F as 10, so in order to increase the value of P, we have to divide the F by a smaller A. the small the A, the bigger the P.
so easy speaking. to have a big big P ( very sharp), u must have very small A. tat is y, if u sharpen your edge to a smaller angle, u get a better edge, but of cos if your edge is smaller, it will have less materail so easy to wear out. i hope u can understand so far. i am trying to simplify the mechancial term alrealy. ok so... i will chose tanto.
in spear, there willl only be one sharp tip whihc is the head. but tanto has two. one on the tip , the other is between the tip and the main cutting edge. ( its hard to explain in word) and tanto's area of contact point, i mean the tip uaually larger (but enough to stab) so have a stronger tip. the tanto shape is like this ( hey man, i using singlish to explain here cos too hard to explian in english). the shape of tanto. starting from the end of the blade ( which is at the handle part) the blade usually goes straight toward. then it reach to a tip and it moves up about 40 degree up to the end tip. so from the end tip and the first tip. there is a small stright edge. this edge can be use for chisel. so u can use it for chipping wood which is very difficut if u used a spear point.. there are also some bad point on tanto and many other good point on tanto too as well as spear..
i can explain more.. but not now.. i need to sleep now. its 6am!!!
c ya.. do take care..
