I never Need to sharpen my knife. Who else can say that ?

I've gone the other way . I thought it would be anarchist , perverse , bad a$$ to carry one of those break off blade utility knives and never break off a segment ; just sharpen it . And I do .
It's not my """EDC""" it is just a knife I carry to work in my knife wallet and use now and again .
No image.
It is called a :

HOTO Box Cutter Utility Knife, SK5 Retractable Box Cutter, All-Covered Design, Blackened Antirust, 8-section Blade,​

It is one of the few these days that does not have steel guides that dull the blade after the blade has been slid open and closed a few times ; what a racket that is .
Took me a while to find what I wanted but I am very happy with it .

PS : before this I often touched up brand new box knife blades .Including radiousing the transition shoulder at the top of the sharpening bevel . You know , to make them "adequately sharp" . From there I would just fully resharpen them when dull rather than replace the blade . I have one old non retractable Stanley handle that was my Dad's and it has got to be like sixty years old or more . I use it most days but for a very particular operation at work . Had to make a cover / sheath for over the blade .

This isn't what you asked for but is what I got to put up .
 
I haven't had to sharpen my K390 knives yet, and I suspect I won't need to for quite some time.

EDIT: The formatting of OP was a bit confusing and I missed the point of this thread I guess. Ah well..

I think is was ~ smart guys just replace the blade .
Why sharpen ?

I'm not that smart yet .

PS : I was carrying and using K390 today and loving it .
Being not all that smart I polished the edge just a day or two ago .
What do I know ?
 
ok.... I'll play, but I don't know why, disposable box cutters don't seem like something people want to ogle

What’s that beige one, please? Hell I’d take a list of all of em if you’d oblige me, very nice selection.

Thank you, sir. The tan one is the Kizer CO1C UTI 2. It’s a very capable top liner lock that’s comfortable in the hand.

To its right is the minimalist Magnus SideClick Utility Blade knife. This is produced by the same gent from New Zealand who originated the spectacular ClickShift line of lever actuated titanium pens.

Directly above the Kizer is the Exceed Designs TiRant Razor V3 utility knife. This is a top quality flipper that comes from the manufacturer with enough spare to darn near build yourself a second knife. :) They now have a newer TiRant Ultra model that is more expensive, but which has a unique swap mechanism that allows the user to separately purchase a whole slew of replacement blades other than just the utility blade carrier.

Continuing on, at the far left of the top row is the TacKnives Zipper D/A OTF utility blade. It feels well made, features a deep carry pocket clip, a snappy action and has been dead reliable for me thus far.

Next to it is a Chinese plunge lock folder made by a company calling themselves Flissa. It’s advertised as a titanium utility folder, but IIRC, while the blade carrier mechanism is all Ti, the handle portion is aluminum. It feels extremely well made, regardless. Depressing the plunge lock button is the only way to deploy the blade, which may be a minor annoyance to some. My take is that delivers really good value at around $35.

In the middle of the top row is another all titanium Chinese offering from a company called Tgzuo (yes, I spelled that correctly) which they identify as their 3-in-1 Retractable Blade Utility Knife. This is a very solidly constructed chunk of titanium. Being that it’s slide actuated, the smoothness of the action is occasionally rendered less than optimal due to minor, intermittent Ti on Ti galling issues. Otherwise though, this thing should be able to survive Armageddon.

I should mention that Tgzuo also manufactures an all titanium flipper utility folder which is equally outstanding. I didn’t include it in last night’s picture because it was at work, but this thing is a phenomenal value for the money. Honest to God, the flipper detent on this is better tuned than the actions on some top name folders I own costing literally hundreds of dollars more. I have one of my OKNIFE ceramic utility blades loaded into this one.

The green handled D/A OTF is from a Chinese company called Caressolove. It appears to now be discontinued, and in all honesty, I couldn’t really recommend it anyway. It had the unique issue where the blade holder carriage wouldn’t accept standard dimension utility blades. After a little investigation, I discovered that it shipped with utility blades that had the same length cutting edge as any standard utility blade, but the flat, top edges were slightly narrower than standard. The blade carrier dimensions matched this profile almost exactly and, as a result, you couldn’t push a standard utility blade in far enough to get it to lock in place. I eventually took it apart and, using an extremely thin diamond cut-off disc on a Dremel, was able to deepen the slot in the critical area far enough for standard blades to fit. Now it’s a phenomenal little utility knife, but legitimately was a bit of a hassle to make it so.

Ti utility knife from Aerocrafted.
Cool, sort of pricey. I got 2 modern Ti and one aluminum, plus a couple of the old timey ones from my dear old Dad. Also have a multiple lifetime of blades. Why am I f@rting with knives?
 
I got these two no-name OTF boxcutters for under $20 each and really didn't expect much.
But they're both aluminum and work well.
The orange-colored knife is built better than the silver one.

Purely as an ‘EDC utility knife’ public service announcement, I would like to warn people off of ever purchasing the Pichi G9. I owned this knife for many years, probably over a decade. It was one of the first slick, cool, EDC-style utility knives I ever purchased. Prior to that, my utility knives were all made by Milwaukee, Stanley or DeWalt. I kept it in a kitchen drawer where it was always handy for opening packages and breaking down cardboard boxes.

Now, to be scrupulously fair, there is absolutely not a thing in the world wrong with either the materials, quality of construction or fit and finish of this product. In those categories, it gets straight As across the board. So how then could I possibly have a complaint about it?

Well unfortunately, the people behind the design of this knife have apparently never heard of human factors engineering. It’s not that it’s uncomfortable to hold from an ergonomic standpoint. It’s just that the design and implementation of their three position lever mechanism couldn’t be more confounding.

Overall, we’re looking at sort of a clamshell type design. In one position, the lever locks the clamshell in place (either with the blade deployed or retracted). In another position, the lever allows you to physically twist the clamshell open just enough for the blade to slide in or out. In the third position, the lever allows you to twist the clamshell all the way open when swapping out blades.

The lesser problem is that this design makes it virtually impossible for you to manipulate the lever one-handed when holding the knife as you would to cut things. By itself, I wouldn’t characterize this as much more than an annoyance.

The far greater problem is that there’s absolutely no intuitive feel for which physical position of the lever controls which function. Worse still, if you try to slightly twist open the clamshell, to either extend or retract the blade, while the lever is in the wrong position, then the entire mechanism locks up. Now you’re left to fumble around with this thing trying to force the clamshell back into a position where it becomes unstuck.

What’s truly remarkable is how you can own this thing for years without the UI ever becoming any more natural or intuitive. Finally, about six months ago, after having this stupid effing mechanism jam up on me for the 7932nd time, I threw the entire thing into the floor with such unimaginable force and ferocity that the piece of crap exploded into a hundred pieces and the titanium clamshell on one side completely sheared into two separate pieces near the pivot end.

Thankfully, I don’t lose my temper like this very often. But when I do, I typically feel ashamed afterward at what I recognize as a transient lack of maturity. In this case, however, there was no regret whatsoever. There was only unbridled joy at finally being freed from the torture of this diabolical object. Could I have just given it to someone else rather than obliterating it? Sure. But why would I want to be responsible for inflicting this abomination upon any other person?

It needed to be destroyed.

They all need to be destroyed.

RIP POS.

😊

Too bad you guys don't have "Utility Knife Forums" where you can sing the praises of never having to sharpen for all the world to see. ☺️

(In truth, I strop my utility razor blades until they no longer do the job intended...some things are just embedded.)

I've seen video shorts of old razor blade sharpeners and strops. We used to be people that got all the use possible from things before disposing of them. Now of course it's all disposable. I too try to strop my razor blades more just because I can but it would be neat to see a company bring back one of the sharpeners.
