what is the difference between the kershaw 1970 and the 1660 , in regarding the opening speed ?

I don't believe you would notice any difference between the two, honestly the speedsafe mechanism works in the blink of an eye. One would need some kind of high motion camera to differenciate between the two

I have not dealt with the 1660 model personally so I cannot accurately comment on the opening speed in comparison to this model. However, what I can say is that the 1970 opening speed is more than sufficient for me. I've had the knife over a year and the flip speed of the knife hasn't degraded at all, despite a large amount of use. The speed is quick and efficient and I have no complaints about it.

The 1660 has a quicker opening speed than this knife. but the 1970 does open fairly quickly and very smoothly.

Sorry I don't have the 660 but the 270 is silent and very powerful. Really moves the air and I can run it all night.

Hi, The 660s are not new. They are remans. The 390 is the newest one. I very much like the one I have. I have no complaints and highly recommend it. Lane

I like the rat 1, great blade, get satin blade the black is paint & doesn't wear well . The handle is strong & comfortable .Razor sharp out of the box & I prefer the drop pt. blade shape. Kershaw knives are well made & sharp but I would choose the Rat.

1660CKT is the Leek (1660) in satin black. 1660N3X is not a model of that Kershaw has ever produced to my records.

My understanding is O1 is slightly better and the change was a factory decision. I may be wrong about it but either one is good, outstanding even. I have the Laredo in what I believe is SK5 and a Natchez in O1 and have sharpened both, neither seemed better at sharpeneing or edge retention or wear. Both of mine are shaving sharp and yes I have used them outdoors with no problems just be sensable and don't start whacking on the handles. Both blade steels I highly recommended. The only steel (layered) that I know to be better is the San Mai but the price increase is substantial. I hope this helps you.

This is a little quicker and leaner than the Kramer knife. If the Kramer is what I am familiar with, the Reserve is easier to care for since it is not carbon steel. The carbon steel will rust " patina" if you don't wash immediately.

Older kershaws were made in the USA and at least some have USA near the blade pivot point. The new ones say CHINA in this area. You probably have a good one.

Not sure. 750 is the artisan series only sold by higher end kitchen stores. Has better book by the actual chef and the biggest 2.2 HP motor as well as 40% quieter than older versions.

I just bought the 45 and the only difference I saw between the two at the store was that the 65 has a digital display. I'm really happy with the 45 and I don't think it is worth the extra money. Also, check at your local stores before you order because I got mine from Kohls and there was a $50 rebate included.

Not sure what Gerber you have but my Gerber & Kershaw are easier to open but what more to you want from a cheaper knife

One difference is that this has a 75oz reservoir vs the 60oz reservoir in the B70. I don't know if the internals are any different. I hope they have improved the durability of the machine. It is strange there are so few reviews of this new machine.

Hi, not sure what the difference is exactly, but I must admit that I find this one much better than the previous one. It is lighter and more durable so I fully recommend getting 83 slow. Sorry I can't be more of help

Check out Kershaw speed safe. Its an over center cam. When closed, stays closed. Some pressure on the back of the blade and its assisted open.

To be completely honest, I don't know that there is a difference. At first I thought the motor might be a bit stronger in the 1700, but they both say 450 watt. Sorry I couldn't help any further than that.

Ive had no problems with the TAC force knife and is less expensive its also the right size for me. The assisted open is ok also works fine and hasnt fallen apart. I dont own a kershaw but have checked them out and id rather buy a Gerber if im going to pay money for a real good knife, but i have 3 tac force knives and they all work for me.

The difference is that the FMM250 requires a tool (allen-provided on new purchase) to install and remove blades and other attachments and the FMM250Q has a built in lever action for a quick action install/removal of blades. It is made in Germany, at least that's what my tool reads on tool label.
