You can't tell easily.   Steel is hardened at very high temperature (red hot), then tempered at low heat. At low heat, the steel color may not change. So you might have changed the quality of part of the knife.   dcarch
There are 200 main dialects in China, and about 8,000 variations of the dialects. Each dialect regent has a different style of local cooking.   In Japan, there are two major dialects, Eastern and Western.   dcarch
Have I missed something here? I am totally puzzled!   1. What is the budget? 2. Where do you live? 3. Do you own your house? Or are you in an apartment? 4. How big is your kitchen? 5. How many in your family? 6. Do you hunt? 7. Do you have a fulltime job? 8. Do you want to be a gourmet cook? or just a home cook? 9. Will you be moving to a new house sometime in the future ? 10.----------   Without knowing a lot more, I don't see advices mean too much.   dcarch  dcarch
Now back to cooking. What do heat sinks have to do with cooking?   I am interest in heat sinks because you may see in my collection of heat sinks, there are two for Peltier Junction devices. Attached to a cookware, It is capable of either keeping food cold or hot.   I mentioned "Heat Pipe", Heat pipe can make a very efficient heat conductor to heat up the inside of, say a turkey.   dcarch
 Really? Ok, so I guess having actually used the stuff was a figment of my imagination. See my response above. Diodes, (after selenium rectifiers, which came with their own heat sinks) mostly came in fours for full wave bridge rectification. On a circuit board, four heatsinks will take up a lot of very expensive circuit board real estate.  No, not in the science but it doesn't take a genius to realize the changes that have taken place in electronics since the 60's and that...
" My first job out of high school (back in the 60's ) was in the electronics industry. We used that exact same material so I can say it's definitely heat sink material. Sure, heat sink material is aluminum,  You can find a million things make with aluminum.   We got it in something like 3 foot lengths and cut it up. It's for use with stud mounted rectifiers or diodes. You drill and tap a hole in the center of the end and screw the diode into it."   I don't see how...
If you go to the link I posted above, look thru the material, you will see the design allows 90 degree connection, 45 degree connections or 135 degree connection. You will also see the similarities of post designs very similar to the item in question here. dcarch
All extruded pole connectors come with plastic top cap, side caps and bottom base as part of the same system, which will eliminate exposed corners. If you go to the bottom diagrams in the link, you will see how the shape allows connecting flexibility. dcarch
The heat sinks with a solid center shaft are heat sinks for high power LEDs. But again, the whole idea of heat sinks is lots of surface area to radiate heat.   If you Google LED heat sinks, you will see they all have lots and lots of fins.   dcarch   Do check out this link:   It says: Application - accessories for exhibition booths
