Broke my all time favorite knife (whimper)

[Weiss]

Sorry to hear about the broken blade on a much enjoyed tool. I always liked that model, but never purchased one. And since I know I am prone to doing non knife things with knives, I have a couple of Cold Steels for most such occasions, a 4-Max Scout (heavier than the Rukus, with a quarter-inch shorter blade), and an SR1 Lite (a little lighter than the Rukus, with a slightly shorter blade).

Meanwhile, good to see that you have backups, particularly since that's a discontinued model.

Perhaps Santa Claus will remedy this come Christmas?

Well this sucks. I’m very sorry to read this.

Sorry you broke your favorite knife, but I can't say that I'm shocked. It's the reason I never pry with a folding knife, no matter how "hard use" it's supposed to be.

Yes, that's the way I'm looking at it now. I was lucky to have a knife this good for so long and that served me so well.

Hard to quantify how lightly the leverage force was. I was being careful not to use too much force. Seemed to break awfully easily, especially at the thick part of the blade. I've intentionally broken blades before just to see how much force it takes. Those blades took a whole lot more force to break. I remember an old video that Deadbox did of prying and abusing a Benchmade (Proper?), which was much smaller and and thinner and took far more force than I put on my Rukus.

I'm kind of fixed on the appearance of the grain at the break point. It doesn't look right. Maybe someone like @Larrin or BluntCut MetalWorks could say more.

Looks like - a light pry then with a slight wrist twist and tug clockwise = cascaded failure. Ruptured corner lead to cascade 1, cascade 2 is almost vertical. Pic doesn't has clarity+res to see grain but bright & dull appearance due to fracture type.

Thank you, Luong. Does the two-tone coloration of the grain mean anything to you? Is that the bright/dull difference you see?

Sorry for your loss. I wish I could say I've never done that but....

Intragrainular(across grain) has flatter surface thus brighter vs intergranular(between grain, grain boundaries) rougher surface hence dimmer/duller. Pic doesn't has sufficient resolution to see grain size... nevertheless looks fine (per std ht 60rc).

Normally a folding knife will break mechanically before the steel itself breaks or is used down to the spine, used "normally" the original owner will likely pass before a single decent blade is used/sharpened to the spine, example of this would be my dads leatherman micra blade, decades of backpacking use later and unfortunately outlasted him, that said ---
im impressed the mechanics of the knife held up to your brand of use.
