DeWalt Retractable Utility Knife Review - Model DW10035 

Found the utility knife when we moved in to our house... couldn’t figure out how to change the blade!! Thanks man!!

THANK YOU! Could NOT remember how to change the blade and learned not only how to do that but other little tricks that make these arthritic fingers so much happier. I appreciate your speed and thoroughness of your review. I agree: DeWalt delivers!

Im thankful for you just changing a blade on this. I thought the black button was not grabbing the blade to push back far enough and i know to use the front crevice/dip slot. It just was not grabbing. I did slime it up a bit and that helps. So I knew I was doing mechanics correctly.

I felt so damn stupid. This knife came with my tape measure. I can't believe I had to watch an instructional video on installing a utility knife blade. Thanks a million. 🤦

HOW TO INSERT & REMOVE BLADES: A major number of negative reviews, and comments pertain to the seeming inability to insert & remove blades. This is due to Dewalt's inadequate blade insertion instructions, and not due to a faulty blade insertion/ removal mechanism. However Dewalt needs a less tricky more user friendly mechanism. Ease of Blade insertion and removal is "tricky" not difficult, or impossible once mastered, as follows: BLADE INSERTION: 1. Move the blade slider to full forward as if you were extending a blade to its fully extended position. This fully extended position of that blade slider is needed both to remove, & to insert a blade. 2. Initially Insert the blade tip at a 45° angle to the top of the blade cavity (not the flat side, but the top of the blade cavity) until insertion stops at about 1/4 of the way in. Be sure the flat of the blade is not inserted at any angle to the flat of the blade cavity, which it will do easily. Unless and until the flat of the blade is exactly lined up with the flat of the blade cavity you will not be able to proceed to steps 3. thru 5. below. 3. Straighten the top of the blade from its initial 45° angle to the top of the blade cavity in step 2 above, to instead where the top of the blade is totally parallel to the top of the blade cavity. I emphasize the word totally here. This is the tricky part. By totally parallel above I mean so the top of the blade is pressed against the top of the blade cavity totally. The blade will then slide further into the cavity to where only the last of the two notches atop the blade is yet visible. 4. Press the blade release button hard while executing step 5 below. Note: This blade release button does not have to be pressed until step 5. below. 5. While being sure the top of the blade is still totally against the top of the blade cavity ( this is the tricky part per step 3. above). Then in that event with the blade release button pressed hard, per step 4. above, the blade should then easily glide completely into the blade cavity, and lock in place. Wallah! BLADE REMOVAL: 1. Fully extend the blade.. 2. Press the blade release button hard while executing step 3. below. An even harder press of the blade release button may be needed to release the blade than the hard press of it needed for blade insertion. Ridiculously hard! 3. Be sure the top of the blade is pressed against the top of the blade cavity, whereby with the blade release button pressed extremely hard the blade should then remove easily. Note: If the blade does not then remove easily then in that event: A. Again be sure the top of the blade is pressed against the top of the blade cavity. B. And/ or a little gentle jiggling. C. And or a relaxing, and repressing ( again very hard) of the blade release button may be needed. Wallah!

I bought me one of these while back and I forgot instructions. Thank you for showing how to replace blade and storage for blades.

Dude I couldn’t even figure out how to work the damn thing, so thank you! Big fan of the blade storage

Milwaukee has one that flip/swing out and stores 5 blades check it out it's is sweet.

totally awesome video I got one of these knives I could not figure out how to put a blade in it I'm used to working with cheap stuff and of course cutting my hands quite a bit so when I had a chance to buy this one for $6 on sale I grabbed it it was normally $18 thank you for explaining everything it was a great video

Thanks for that. NOW I know how to change the blades !! Simply couldn’t figure that part out. Cheers !!

Thanks I was given this knife and didn't know how to change blade

Good overall review. Thanks.

Finally just opened my new dewalt knife and I can’t even put the blade In.... really Frustrated

Thank you my guy, you taught me how to open the truck that I didn't even know about and the push to slide in the blade.

I bought a slightly different model it’s not very user friendly. I had to watch a company video to install the first blade. Hopefully it will provide good service

Bought one and ran into 2 problems. #1: The remnants of the card were jammed into the blade area. Needle nose pliers and 20 minutes worth of coaxing finally removed all the paper shreds. I considered burning it out! #2: Inserted a blade, it disappeared into the bowels of the knife, little tab button won't engage. Summary: Paperweight. $13 gone.

I know I know this video is old and blah blah blah lolol but how come not a single person in any video I've watched talks about the fact you can lock it from folding open if you do have a blade loaded in it?? Do people just not know about it or something?? Do people not play with the new tools they just bought😂😂lolol.?? That was something I found out about within 2 minutes of owning it!! But in case you really had no idea. Here's how. 1. Make sure blade is loaded! 2. Close the knife all the way to it being folded closed! 3. Push down on the blade slide and slide it to the half way point where it locks and boom!! Now your knife is locked completely folded shut and will not open until you pull the blade slide back to closed position!!! Hope some one or every one learned from this comment!! Like stated above I know how old this video is but I watched every single video on this knife and not a single one of guys mentioned it and I thought it was the best part as I have a 3 Y/O son who loves to be just like dad and is getting into my tools!

Thanks for the info.

Go to point

to those that still need help: your blade may not be slid open all the way. i could not get mine out until I figured that out. I pressed up on the slider harder and it finally clicked one last time to fully extend the blade, then it came right out after pressing the black button.

Can't get mine to retract all the way

the locking mechanism failed for me on this knife. it buckled in and snapped closed on my hand and caused a serious enough injury to require stitches

thank you

Why didn't you show how to put the blade back in?

Why don’t you demonstrate putting the blades back in the knife?!? That is messed up! It takes forever!

Thank you.

This knife is really a piece of sit, i bought 3 already all have the same problem ,when you change a new blade the blade can't hold and always fall out, don't buy

I was so disappointed it doesn't work properly, I don't wanna think someone at the quality department is not doing a good job, I don't only say it for a 12 buck utility knife, like even their battery packs are garbage and so expensive, I'm done with dewalt.

You should pin that dude Matt's comment on how to insert the blade. He helped me & my mother.

Try the blades supplied in the handle and the knife works great.Stanley blades will not work.Take Care

How TF do you put the new blade in?

If you cannot figure out how to change blade ? You are TSA approved and free to travel anywhere in the world. Except Bikini island . Its still glowing so please leave that to experts .

They changed the design. The storage compartment is now a tab and not a button. And the blades are not as earth to change. Quality has gone way down from the video shown. I have a 13 dollar piece of trash right now.

You show how to take the blade out but not how you put it in. And that's where the fun really begins. Piece of crap knife.

way to show us how to change the blade...

Must use Dewalt blades.

It’s so effective it’s ineffective. Just want to open up the blade compartment. Thanks a lot, De WAIT. . Wish I could bill you for this isht waste of time
