for construction work just buy cheap replaceable utility knives with replaceable blades instead of messing up a nice knife unless you really enjoy using your knives hard for work and seeing how they hold up
Along those lines you can get hawkbill blades for Olfa 34B/CKB-2 craft knives, as well as titanium pocket knife styled handles for these types of blades. Both sliding (most lock rather than simply tightened with friction) or ones that open like regular pocket knives. The blades can be purchased for about $11, but the knives themselves vary from cheap to well over $100. I have one coming that was about $40 shipped, as well as a hawkbill blade, but they're both taking the slow boat from China and I haven't received them yet.
The blade itself is 8Cr, or at least it claims to be. Hard to be sure, considering the source. If it is, then it's more than acceptable for $11 (even if it's lesser than 8Cr, oh well). Of course, it's resharpenable, but at $11 can still be considered "disposable" and replaced with a new one when you get tired of sharpening it or it's damaged beyond repair (hawkbill tips aren't known for being very robust).
An even more disposable alternative might be hawkbill utility blades (often described as "concave", for purposes of searching). These can be problematic though. The most immediate problem is
finding them. They're far less common, and can be found with or without holes, which may or may not line up with the particular mechanism (pay attention to the notches too). For obvious reasons the ones I tried were Stanley brand, and the 5 pack I bought off Amazon actually shipped from Vilnius, Lithuania. The other problem is compatability. I assume these Stanley blades will fit in a standard Stanley utility knife (I haven't tried, and believe it or not, don't own one). The issue is that they're shorter on the side that has no edge, and longer on the edged side (in relation to the notches). They do not fit in the titanium handled framelock flipper utility knife I own (not without grinding the blade down, and it either didn't fit in any of the titanium sliding tools I owned, or it was a bad idea for reasons that should be obvious looking at these pictures.

The one I found that works great is by Titaner. Normally I'm not a fan of this style because blades with holes like this are extremely uncommon and/or limited in choices, plus blade changes aren't as easy and there's fiddly bits to lose, but for me it's an acceptable compromise, it works well, and I do like the hawkbill for certain uses. The tip doesn't stick out and the edge isn't exposed. Looks pretty fetching in blurple too, I think.
