He's over 8 years old which is fairly old for a giant breed. Some books say 6-8 years average. My last made it to only 5 and a half before he went from bloat.Po' ol' guy! how old is he? Funny thing about an old blind deaf dog, they can adapt pretty well especially with owner support.
He does do fine. The only problems are when he is half sleeping and someone comes up and gets close or touches him. He gets startled.
The cataracts only bothers him at night when he stares in the distance at sha[pes he can't figure out. He freezes up trying to process what can't be understood so I just describe to him what he's looking at and tell him no one is there. He's fine after that. Also when he sees a car he takes a second to figure out if it's moving or not. Sometimes streetlights appear as cars at night to him and he doesn't want to step down off the curb.
He's always been great about walking near streets and by cars. He's trained to get off the road onto a curb when he see's one moving. I've seen him push people walking him on the leash up onto the curb off the road when a car goes by. Now, I'll warn them ahead of time if somebody else walks him that if he plants his shoulder on their hips and pushes that he thinks a cars coming and he's protecting them.
That's just his nature.

It's tougher, has more wear resistance and is a bit more resistant to corrosion. I like O-1 as well but they are different steels. O-1 is finer grained, Cruware has more carbides for improved wear resistance.

Mr.Moe, I doubt if anybody around here would look down on you for a question. I know I ask my share and people are polite and helpful with me. This forum is a lot nicer than a lot of others.I hope no one minds my total newb question. Don't have a clue about steel, just starting to learn and figure things out. How is the corrosion resistance compared to carbon steel like 1095? Thanks.
Anyway, Cruware will have some free chrome, tungsten and maybe moly in it's composition after it's heat treat which makes it a little more resistant to corrosion than the simple high carbon steels which just contain mainly iron carbides.
It's not as corrosion resistant as D2, but is more corrosion resistant than O-1, etc. It's somewhere in the middle depending on the heat treat, final hardness, exact specs of the steels ( the posted specs are usually *not over X.XX %. It may have a Not under number as well. ) The differences in the composition, while still in spec do cause minor variations in the attributes of the steel. Ading more carbon can cause more chrome carbides and there will be less free chrome, for instance.
The heat treat itself will cause differences in the amount of elements tied up in carbides, and the amount that is free ( free chrome will give the corrosion resistance in steels. Moly and the others will also but to a lesser extent)
Powder steels are often more consistent from batch to batch but there will still be minor variations, as well as "tramp" elements which are basically things like copper or other elements not in the "recipe" which found it's way into the melt from recycled steel.
Ingot steels are more often going to have variances from batch to batch. One steel supplier had a sheet of W2 tested and it's composition was slightly different on the other end of the steel :0
Knifemakers will often make test knives with a new batch of the same steel ( say D2 from two different batches from the same supplier) to fine tune the heat treat to that batch of steel. Recall consistency in production is very important.
Also keep in mind the finish of the knife will determine some corrosion resistance. The same steels at the same hardness with the same grind should act about the same, right? Now mirror polish one. It becomes more corrosion resistant, right? Scratch a knife up and it gives the rust a great place to get started, as well as for corrosive elements and salts to hide from wipedowns.
As complicated as it all sounds, believe me it's even more complicated with things I don't know and understand. I'm a hobbyist knife collector not a metallurgist. :)

That seems to conflict with what I found on the net about the steel. Should be more resistant than D2??? Now I am confused.The Mastiff wrote:It's not as corrosion resistant as D2, but is more corrosion resistant than O-1, etc. It's somewhere in the middle depending on the heat treat, final hardness, exact specs of the steels Joe
"CRU-WEAR is an air-hardening tool steel, heat treatable to HRC 60-65. Designed as an upgrade to D2, it offers better wear resistance, greater toughness and higher attainable hardness. Compared to the chemistry of D2, (D2 = 1.55% carbon, 11.5% chromium, 0.8% vanadium, and 0.9% molybdenum), CRU-WEAR has less carbon and less chromium, but more vanadium and tungsten. Both D2 and CRU-WEAR contain carbides for wear resistance, but CRU-WEAR has more vanadium carbides than D2. Vanadium carbides are harder than chromium carbides and are much more effective in providing wear resistance. Because CRU-WEAR contains less carbon than D2, its overall carbide volume is lower, making it tougher than D2."

They both say the same thing.That seems to conflict with what I found on the net about the steel. Should be more resistant than D2??? Now I am confused.

D2 is more corrosion resistant than Cru-Wear. Cru-Wear is more abrasion resistant than D2. Two different types of resistance are being discussed here, resistance to corrosion and resistance to abrasion.jtoler_9 wrote:That seems to conflict with what I found on the net about the steel.

Felt the same about SS vs. nonSS and feel the same, feverish....got one inbound....Mr_Moe wrote:So far I've shied away from non-stainless steels. This sounds like a good opportunity to try some. And I've always wanted to have a Mule with a nice cerakote finish... so many options. Mule fever... sigh.
