My google fu isn't up to this so I need help please.

I need to replace a snap off blade utility knife with another having a very specific feature.

The original is Chinese made and was bought in Asia. The brand Ningbo Assist isn't available in the UK as far as I can see so I can't just buy another.

The must-have feature is a screw locking clamp that works on the very front of the blade to resist it being pushed back, pulled out or wobbling.
This improves the use of this type of knife enormously and is far better than just a screw locking knob at the back.

The thread will probably be more interesting to all if people want to recomend their favorites, but nothing without a front blade clamp is going to fly for me personally.

Hoping someone can help me find a good candidate. Cheers

My weapon of choice is the Olfa L5-AL X design, which can use their "special" black blades.
I thought my old Stanley knife blades were sharp until I tried these....

However, for marquetry I still use my old brass handle Swann-Morton, with 10A blades. You can still find 'em on eBay now and then....

Do you know what makes these black blades especially sharp ? Are these they thinner than normal, shallower grind, harder steel ?
 
Traditionally people used to sharpen "utility"knives. These ready sharpened snap-off blades were designed for schools and other institutions with unskilled beginners.

Described as "ultra sharp"....and yes, they are!
In truth I'd probably use the Olfa for marquetry, but I'm too used to the old-fashioned, less bulky S-M handle. It's a toss-up which is sharper, a pukka scalpel blade or the black Olfa.
All I remember is that the black jobs taper from about half-a-mill at their widest/thickest point...my model uses the 18mm blades, by the way...I think there's also a 9mm version?
 
Personally I love these:

They do clamp firmly at the very front of the handle - the knob at the rear slides the two halves against each other until they are wedged firmly against the blade in a vice-like grip.
I've owned this in the 9mm size.
A good design with one flaw when I owned it. The screw thread on the yellow knob at the back is quite coarse and as a result it quickly became loose whenever the knife was in use. This was annoying and it ultimately went in the bin.
I haven't tried it in the 18mm size or recently to see if they changed the screw thread to fix the problem.

The snap off blade has two useful features compared to an ordinary stanley knife blade, one is multiple points, the other is the length when a new blade is extended further than intended. This second "misuse" is handy for deep straight cuts thick foam - shadowfoam or occasional celotex.

Disposable blade knives are not just about unskilled users. They save time that would wasted on sharpening, they "allow" a blade to be used to destruction in a way that you would never do with a fixed blade, and their thin steel and sharp edge do give a slicing performance that would take a lot more time and effort to achieve in a fixed blade.

Have you noticed that scalpel blades feel hair splittingly sharp for about the first 6-10 feet of cutting and then become merely "very sharp" and still better than a new ordinary replaceable blade.
A lesson learned cutting shadowfoam for toolboxes is that after cutting in 3 or at most 4 tools, you fit a new scalpel blade. The old ones are still at 90% so save them for other jobs.

Irwin makes almost identical ones - I have one. They;re metal rather than plastic too.
