Additional Information

Additional Information

Westcott Titanium Bonded 45mm Rotary Cutter (16370) is rated 4.6 out of 5 by 43.
Rated 3 out of 5 by from Sharp! The blades on this rotary cutter are very sharp. I used it to square up the edges on a purse that I was sewing and it easily cut through one area that had 14 layers of fabric. This cutter is very light weight, fits my hand well and is comfortable to use. I do have difficulty with the retractable blade guard which is the reason for the 3 star rating. The lock button to release and slide the blade guard is very difficult to operate. I became so frustrated trying to retract the blade guard, that at one point I had to put us both in time out . When I went back and tried again, I was able to retract the blade guard. I will keep it in my travel sewing kit as it is very light weight, but I will prefer to use a rotary cutter with a smoother retracting blade guard for everyday sewing and crafting.

Rated 5 out of 5 by from Nice effective cutter. The Westcott Rotary Cutter is definitely effective! It is very sharp, so bear that in mind when using the blade. It is rated for medium usage, but I also used it on cardboard without any problems. The user doesn't need to apply undue pressure, because the blade is made for cutting, and that it does. Just remember to put the safety case back on the blade when the Westcott Rotary Cutter isn't being used, because that sharp blade works so very well.

Rated 3 out of 5 by from Westcott Rotary Blade Westcott Titanium Bonded 45mm Sewing Rotary: 3 times harder than untreated stainless steel blades Comes with a safety shield Quick and easy replacement blades Great little item. Blade is sharp and high quality Titanium stainless steel. The thumb level used to open and close plastic blade cover needs improvement. very hard to use and cheap. I struggled to cut thru several types of fabric even though blade appears very sharp.

Rated 5 out of 5 by from Very Useful! This is a very useful cutter. I thought that I would only use it on fabrics, but I was wrong. I have found many uses for it around the house. It cuts paper with ease especially a stack. I also use it for opening packages! It works much better than a boxcutter. Another great use was for cutting up herbs. I changed the blade and it was awesome!

Rated 5 out of 5 by from Good but very sharp Very good. Very Very Sharp. The lever pushing the blade up was a little hard to move. It got easier with use. This is VERY SHARP. I put the cutter down to adjust my material, I forgot to close the blade. I moved my arm over the blade by accident and it cut my arm. It works great cuts very quickly without much effort.

Rated 4 out of 5 by from Easy cutting I make quilts and this rotary cutter is a perfect tool for cutting multiple layers of fabric. It is easy to use, super sharp, and the blade replacement is simple. It fit my smaller hands just fine and handled well. And the sliding safety shield is perfect for storage and to keep the blade away from fingers.

Rated 5 out of 5 by from Must have for your crafting needs This is perfect for straight line paper cutting and vinyl cutting down rolls. I buy my Oracle 651 one in rolls and love that i can quickly cut off a 12x12 piece quickly in a straight line. I do have a cutting mat with measurements so I don't have to worry about surface placement when using.

Rated 2 out of 5 by from Rolls smooth Thr roll was smooth and easy but the safety shield seemed to stick upon opening. The blade did not last as long as hoped and the handle was thin for gripping. A good amount of pressure was needed to get through 4 layers of cotton fabric but handles 2 layers better.

Q & A

How does the washer go back on? Top, bottom, inside the blade outside the blade? It doesn't say which way it goes, it's a total nightmare!

Asked by: Me101
Please see attached for the directions on the rotary cutters.

Trying to put mine back together. Where does the metal washer go on - the front or back? Which way should the bow in the washer be facing?

Asked by: crafter54
The link did not answer the question at all. None of the documentation or pictures show the washer. I found a youtube video for a competing brand that showed where the washer goes - on the back, bowed side to the blade, cup side facing the nut.

In order to cut with this blade, slide down the cover to expose the blade. Then slide across the fabric like a pizza cutter. Please see the picture attached.
