I’ve only been using hand planes for maybe two years. I’ve learned a tremendous amount from reading the articles and blogs from some of the Lumberjocks members and elsewhere online. I thought it would be neat to show some detailed pics from some of the hand planes in my collection.

K7 vs KK7

The first used plane that I purchased was a Keen Kutter KK7. I didn’t know much about planes at the time other than I wanted a jointer plane to flatten a laminated workbench that I still haven’t built! I’ve since added 8 more planes to my collection so I’ve learned a lot from cleaning and tuning them. I recently purchase a K7 so I thought I’d start my Hand Plane Closeups blog with a comparison between the KK7 and the K7.

From the front the only difference is the cast model number.
Note that I just unpacked the K7 so it’s pretty rusty

This is a closeup of the logo on the KK7. Note the shape of the iron as well. It seems hand forged.

This is a closeup of the logo on the K7 iron. The single K Keen Kutter planes were made by Stanley so the iron has the same angles as a Stanley blade of the same era.

KK7 iron and chip breaker on the bottom. The K7 assembly on the top. Look how thick the KK7 assembly is! As a side note, since the KK7 was one of the first planes that I bought, I thought all irons were supposed to be this thick. I was shocked when I bought my first Stanley Bailey plane!

The frog face on the KK7.

The frog face on the K7. Note that the frog screws are screws and not pins. The single K planes are identical to the type 4 Stanley Bedrocks.

The lateral adjust lever on the KK7. I’ve heard references that the KK series of planes were manufactured by the Ohio Tool Co. but I have nothing to compare it to.

The lateral adjust lever on the K7. It has the same half twist as the KK7.

The frog seat on the KK7.

The frog seat on the K7. You can clearly see that it’s an early Bedrock.

The back/bottom of the KK7 frog. Note that there is no mouth adjustment screw.

The back/bottom of the K7 frog. I’ll compare the K7 against at Stanley 606 in a future post.

The KK7 has a rosewood tote and knob. Note the steel hardware.

The K7 has a stained hardwood (beech?) tote and knob. Both the KK7 and the K7 have the low knob. Interestingly the K7 has the Stanley style brass hardware for the tote, but a plain screw for the knob. I believe the hardware on the K7 is original.

Both the KK7 and the K7 iron have the chip breaker screw hole at the top of the iron. For comparison I show the K7 iron at left vs a Stanley (#8 Type 10) iron at right which has the hole at the bottom. Okay so I didn’t take the chip breaker off! But you can see that the iron at right shows only the slot extending toward the top.

So I hope everyone found this informative. I’ll post more in the future as I take apart and tune other planes in my collection.

Cheers,
Sheldon

Interesting, your post suggests my kk6 has the correct frog. My frog looks like yours and the bed of the plane looks the same and it appears that yours has the same small gap between the frog and bed that caused me to assume that mine was a piece together.
