Hey there, so, I am about to get a new Katana for myself and I wanted to try something new. While i want to have something that is quite resitant to bending I also want something that looks well. Now I have to choose between 9260 (monohardened) with a fake Hamon, or a T10 blade with a real Hamon. It is going to be used for full contact practice, so it will be dull, dont worry
Since me and my sparring partner are already a bit more experienced, both over 3 years, the extra flexibility of the 9260 might not be that necessary, but for sure not wrong and I was wondering if the T10 blade would be an suitable option, maybe some of you can help me out with own experiences.
Thank you in advance, and please excuse my language, english is not my mother tongue. Furthermore, I hope you can see my point, explaining something is not something that I would describe as one of my strengths...
Edit: What about a differential hardened 9260 blade?

For full contact practice you need a through hardened (TH) blade not a differentially hardened (DH) one with a hamon. With hard steel on steel contact the very hard edge of a DH blade (60+ HRC) can chip too easily and the soft spine (40 HRC) can take a set. A well heat treated TH blade with 50 - 55 HRC will be more flexible rather than taking a set and the blunt edge still hard enough to avoid saw teeth after steel contact. For this use a spring steel with ca. 0,6 % C is best, 1060, 5160, 9260 or others in this area. A good heat treatment is much more important than the differences between those spring steels. It's possible to make a TH blade with T10 or 1095 steel but blades made of 0,6 % C steel will be tougher.
AndiTheBarvarian: We had this once when a construction site in the neighborhood sucked much power. Some house units did work, some not, some very strange.

christain: Major power fluxes and outages wide-spread all across N.E. Texas, and a big explosion and fire at a Eastman facility in Longview, Tx.

christain: It was just sooo weird. We each have lamps on both sides of the bed. Hers went out but mine stayed on...and they are both plugged into the SAME wall socket?!?! I used to work in the electrical business, and I've never heard of such.

christain: Oh wow...We just had an electrical 'brown-out'. That's never happened here that I remember. Weird thing is, some of the lights went off, others didn't. Dish TV went off. AC shut off. Everything's normal now though. Happened at my sister's next door too. ?

ouroboros: N I could almost buy a small airship with what I'd save 95$ off

ouroboros: Now all I need is an airship!

christain: You'd be the talk of the neighborhood wearing a top hat and swinging a katana around!

ouroboros: I missed the leather steampunk top hat damnitall

christain: I said I MAY do a vinegar treatment. If I do, I'll definitely post pics.

ouroboros: I watched the spearhead fly by...lemme know via some pics how that turns out

christain: Got my Viking spear head just today from the DotD last week! This thing's bad-ass---solid as a rock. I may do a vinegar treatment on it for some artificial aging.
