![]() ![]() ![]() KT enjoyed the s obvious the blade work and finishing of those knifes are a bit better than KTs, but could be a bit improved by filing the thumb placement grooves above the hilt blade join as on KTs.just another added grip help! KT likes the 90 degree twist on his handle rather than the multiple twist but was interesting to see that done! Thanks for posting the video, Ozarks! Apparently the twist was done on KT's knife early in the forging proces, before the blade was hammered out! Maybe you could find a local fellow interested in making knifes and give him a load of spikes in exchange for him making you one! KT likes the twist of the handle on this one, makes a good grip or it could be leather wrapped to be less hard perhaps.įinally, with such a knife you need to keep a very light coat of oil on the blade to prevent rust. Here are a couple of pics of KT's rr spike knife, bought from a local was a learning knife for him to make, but since it fit my hand perfectly, had a nice balanced feel, and a big pommel end on it suitable for either breaking a car window glass in an emergency, or crackin some bad guys head in a moment of survival, KT bought it.it only cost $12 but that was about 20 years ago.the poor maker, Solomon, was selling nuttin at a craft show KT was exhibiting at so KT purchased one nice deer antler handle folder for $35, its a short bladed skinner and this one, just to give him some gas money.remember 20 years ago.to get home! The finished spikes shall conform to the dimensions specified by the purchaser, subject to the permissible variations specified in Table 2-1.Īll finished spiked shall be straight, with well formed heads, sharp points and be free from injurious defects and shall be finished in a workmanlike manner.Knives are nice items to have made from railroad spikes, if you got a local knife maker.they got good quality high carbon steel and work up well. If the spikes fail to meet the third test, they shall be rejected.Ģ.2.9 PERMISSIBLE VARIATIONS IN DIMENSIONS (1968) ![]() Spikes represented by bend tests failing to meet the requirements prescribed in Article 2.2.6a and Article 2.2.6b may be annealed and resubmitted. One bend test of each kind specified in Article 2.2.6a and Article 2.2.6b shall be made from each lot of 5 tons or fraction thereof.ĥ-2-6 AREMA Manual for Railway Engineering When the option in Article 2.2.5 is exercised, one tension test shall be made from each 10-ton lot or fraction thereof.ī. But no, it won't get as hard as another bit of steel with 30 points.Ī. ![]() Or look in chapter 6 of Principles of Heat Treatment of Steel by Krauss for a very good graph.Ī spike or other bit of steel with 20 points of carbon can indeed be hardened. Retained austenite can actually diminish maximum attainable hardness at carbon levels beyond this.) Run an internet image search with the terms "carbon" and "hardness" and a few renditions of this graph will show up. Maximum attainable hardness levels out around 60 or 65 points. The more carbon available, the more martensite which can be formed. The maximum attainable hardness of a given piece of steel versus the carbon content forms a curve on the graph. There is no magic number above which steel will harden or below which it will not. No disrespect meant to a fellow electrician, but I'm going to get nitpicky here. No you cant HT a spike, sorry read about heat treating and you will understand that one needs at least 35 points of carbon to harden a steel ![]()
